2009 San Francisco Electronic Music Festival

This September was the 10th anniversary of the San Francisco Electronic Music Festival, and I had the opportunity to attend two of the performances. To mark the occasion, many of the original participants in the first festival ten years ago came back to perform.

The festival began with a piece by Miya Masaoka (whom Pamela Z jokingly referred to as the “mother of SFEMF” in her introduction). The LED Kimono project not surprisingly featured a kimono with LEDs, worn by dancer Mariko Masaoka-Drew. The dress itself was very pretty and simple, with a large LED array on the right-hand sleeve. Throughout the performance, different patterns were featured on the LEDa, sometimes very subtle with only a few active, and at other times large oscillating rectangular patterns.

The music began with a very traditional koto performance. There some delay, sampling and pitch-shift effects in the background. The koto was mostly struck or plucked, and occasionally bowed. During the section of the performance, there was almost no dance movement. Over time, more electronics came in, initially low, dronaning, and with overtones that sounded vaguely FM or inharmonic, almost like electrical noise.

As more electronic sounds came in, the dancer began to move, very slowly and subtly. Indeed, most of the movement throughout the piece was very subtle and slow, and did not clearly map to the musical material. On the other hand, the LEDs on the dress did match the rhythms and timbral changes. The first came on during and electronic arpeggio that sounded like classic FM synthesis. There were some dramatic swells with the higher FM-like sounds. The music primarily moved between the elements described, with the long drones and then the fast arpeggiation. But the physical movement of the dancer remained slow. As a result, I found myself mostly focused on the LEDs and the dress.

And the end, I stayed to watch the process of Masaoka-Drew being “unplugged” from the dress, and to fully observe the amount of electronics (and wiring) that were required for it to function.

The second set featured Lukas Ligeti performing his own compositions on the marimba lumina. He began slowly, with very low tones, one so low that the amplitude modulation itself became and audible rhythm. He then layered other sounds over these tones, including some vocal samples that sounded like chatters or whispers. Overall , I would describe his music as a cross between classic minimalism, world music, and electronic music. He described what we was doing as using the marimba lumina to play “samples and funny synths” on his laptop, with a focus on samples were collected from his world travels. One could definitely hear some of the instruments and voices from various places around the world, particularly Africa, in his performance.

The final performance of the evening was by Amy X Neuberg. Her performance was a combination of her “electronic cabaret”, which we have heard several times before and reviewed here at CatSynth; and a new work entitled “The Dude Trilogy”, a series of abstract poems for voice and the Blippo Box. The Blippo Box employs chaotic oscillators and modulation, and can be very difficult to control in a predictable way. However, Neuberg manages to perform it in a very poetic way, and more remarkably is able to match her voice to the sounds of the synthesizer. Rapidly changing vowel sounds matched a fast chaotic filter modulation, the rhythms of spoken word material matching the sequences. At other times her high sung tones followed the unstable high electronic pitches. During the piece, a video camera recorded and projected close-ups of her hands manipulating the instrument, including its theremin-like antenna.

Several of her electronic cabaret pieces were familiar from previous programs. They always are very tight and solid, combining voice, electronics and theatre. She did close with one song I had not heard before. It began with her striking the electronic drum pad repeatedly to produce a “banging piano-chord” pattern, which was matched by her vocals. It ended with a solo and fade-out on the Blippo Box, which almost seemed like a spontaneous moment.


The location of the festival, the restored Brava Theater in the Mission District of San Francisco, was itself an attraction. Besides the large theater space and lobby, the deliberately weathered foyer housed the installation The Exchange by Dukoro, the duo of Agnes Szelag and The Normal Conquest. This installation with subtly placed speakers and sounds generated interactively by visitors, complemented the architecture.

The Saturday performance opened with [ruidobello], aka Jorge Bachmann performing his piece Coleoptera_0909 for electronics and video. The piece centered around beetles, or scarabs, who are members of the biological order Coleoptera. Videos of scarabs were projected onto the screen. Some were crawling on skin, some were in dishes, a couple were on a corrugated cadrboard surface that resembled a Q-bert board. Initially the beetles were solitary, but then they started to appear in groups. One particular scene involved one poor scarab being madly chased and grabbed at by another (one can only speculate what was going on here). The sounds were based on recordings of natural sounds from scarabs. In the early part of the piece, the relation to the insect noises was quite transparent (i.e., it “sounded like insects”). Later on, the connection between the performed sounds and the original material became more abstract, and sounded like thick pads with delays, time-stretching and pitch-shifting effects. The piece ended with a scarab taking off in flight, and the sound following suit with an ascending glissando.

[ruidobello] was followed by an electronic performance of Gino Robair’s opera I ,Norton. It is an improvisational piece based on the writings of Norton I, “Emperor of the United States and Protector of Mexico”, and a famous character from San Francisco history. In 1859, Joshua Abraham Norton declared himself Emperor Norton I of the United States, and began to issue a series of decrees, including the dissolution of the United States Congress. The opera is based on the text from these decrees, but in an “open-ended structure [that] allows it to be assembled differently for each performance.”

In this version, Tom Duff played Norton I and read from his various edicts, while the spoken words are processed by three electronic performers Chris Brown, Kristin Miltner and Wobbly. Indeed. all the electronic sounds were based on Tom Duff’s voice. At first, the electronic manipulations kept the words intact through various delay, pitch and time effects; but over time the electronics became more complex, with delay lines or samples short enough for the snippets from the original voice to form completely different timbres, and as such became more detached from the stage performance. I found myself focusing heavily on the video work of Tim Thompson along with the theatrical performance, and the electronic sounds became part of the background. One particularly strong visual moment was when Tom Duff/Norton I built a small “city” out of colored translucent cubes and shining flashlights through them. This illuminated construction was then picked up by the video and projected onto the screen. There was a middle section in which our protagonist appeared to go to sleep (perhaps dreaming) and the electronic music became the focus, with the video playing against the sounds (which were still entirely based on previously sampled vocal material). There was an overall calm pace to the entire opera performance, punctuated by the dramatic proclamations and occasional abrupt shifts in timbre or visuals; and one simply became immersed in the whole experience.

Pamela Z concluded the festival with what she described as an “old-new sandwich” with several short pieces. The first “older” pieces included looped rhythms layered with rich vocal textures and harmonies, with one featuring a dramatic simulation of a manual typewriter complete with carriage return. There was a performance of a piece I had originally seen her perform at room: PIPES back in May. The next piece was the “new” part, a work in progress entitled Baggage Allowance. It opened with a video of a baggage carousel, with various people reciting the contents of their luggage (clothing, toiletries, books, etc.). The contents became a little more unusual over time, as people described confiscated items and even an attempt to hide a knife at LAX. A simulated x-ray of a bag included strange objects like a frog and a gun (actually, I suppose I gun isn’t all that strange). This was set against live electronic processing of vocals as well as other sounds such as the popping of bubble wrap. The final piece was another older work involving delays and dramatic harmonic vocals (it was originally done years ago with hardware effects boxes before being ported to modern laptop computers); as a representation of classic electronic music being redone with modern technology, it was a fitting conclusion to the festival.

CatSynth video: arpeggicat – cat based note randomization

From ChrisLody on YouTube, via matrixsynth.

Okay, so this is one of my more strange experimental ideas. The keyboard at the top of the screen (a Yamaha SY-35) is midi’d into the lower keyboard (a Novation KS-5). The KS-5 is programmed with a simple arpeggio patch I created which can be played from the SY-35. Then I covered the keys of the SY-35 with cat biscuits and let my kitten Daisy loose on it. I was then able to control some aspects of the sound with conrols on the KS-5. I think she got wise to me about half way through as she stopped standing on the keys. Damn kitty!

Dieb13, Djll, Greenlief, Robair, and Ueno at CNMAT

Last Thursday, I found myself back at my old “stomping ground”, the Center for New Music and Audio Technologies (CNMAT) to hear an evening of improvised music.

Dieb13 (aka Dieter Kovacic) opened with a solo set for multiple turntables. It started with a single turntable producing noise/static sounds, and gradually incorporated electrical hums and synthesizer sounds, along with complex repeated rhythms. The rhythmic patterns were sometimes metric, sometimes more stuttering. With three turntables going at once, Kovacic’s performance seemed more “synthesizer” and less “DJ.”

Dieb31 was then joined by Tom Djll (trumpet and electronics), Philip Greenlief (saxophone), Gino Robair (percussion and electronics) and Kenn Ueno (extended vocal techniques). The set began with “scraping sounds”, Robair blowing a small horn against a drum and Greenlief scraping a mouthpiece cover along his tenor sax. Indeed, the acoustic instruments as noise sources dominated the first section of this extended improvisation, before the Blippo Box, the other electronic instruments and Dieb31’s turntables entered. It was interesting to hear how the sounds from the turntables an Ueno’s vocal techniques matched the acoustic instruments, and it was a challenge at times to tell which sounds were acoustic and which sounds were electronic.

Another notable confluence was Ueno’s throat singing set against low-frequency sounds from the turntable and the Blippo Box. There were also contrasting sections with percussive short notes on all the instruments (trumpet, electronics, sax, voice, turntable, percussion) in rapid succession. There was a very soft section with saxophone multiphonics (we have commented on Greenlief’s expertise with multiphonics in the past), vocal whispers, low-level electrical sounds, and a resonant tube; and very loud moments, screeching, high-pitched. One very rhythmic section featured Gino running fan against cymbals and Tom Dill running a similar fan against his trumpet. Greenlief joined in running keys against his sax. The piece ended with loud notes that came to a sudden stop.

This was followed by a much shorter “encore” improvisation, whose memorable moments were the variety of sounds from the turntable, which included an excerpt from a bebop recording and a toilet flushing.

Weekend Cat Blogging and Photo Hunt: Entertainment

We are once again combining Weekend Cat Blogging and the Photo Hunt, where this week’s theme is Entertainment.

Whether or not music is a way of life or entertainment is a question that has been debated since time immemorial. But if you accept that at least some music is entertainment, then we at CatSynth have no shortage of appropriate photos. We don’t even need to dig too deep in the CatSynth Archives to find intersections of Luna and music:


Click on any of the above images to see the full size photo in its original post.

Yes, we are doing a “clip show” this weekend. It actually works out well, though, as I need to rest a bit for medical reasons. Luna is great company when healing. It also gives me a chance to ponder future artistic directions, and that brings us full circle to whether art is a way of life, entertainment, or both.


Weekend Cat Blogging #217 is being hosted by Mog and Meowza.

The Carnival of the Cats will be hosted this Sunday by Kashim, Othello and Salome.

And of course the Friday Ark is at the modulator.

Outsound New Music Summit: Touch the Gear

This is the first of two articles about the Outsound New Music Summit, which took place last week here in San Francisco.

The first night was the Touch the Gear Expo in which the public is invited to try out the musical instruments and equipment of a number of artists from the festival as well as other Outsound events. It was a respectably sized turnout, with a large number of visitors.

I brought the venerable Wacom Graphics Tablet and PC laptop running Open Sound World for people to play.

It often gets attention during performances, and did so at this hands-on event as well. Because it uses familiar gestures in a visually intuitive way, many people were able to start right away experimenting with it making music with phrasing and articulation. I provided a simple example using FM synthesis as well as chance for people to play a phrase from my piece Charmer:Firmament (which uses additive synthesis).

Tom Duff also demonstrated his own custom software in combination with a controller, in this case an M-Audio drum-pad array. One thing we observed in his demo was how much computing power is available on a contemporary machine, like a Macbook Pro, and that for many live electronic-music applications there is more than enough. But somehow, many applications seem to grow to fit the available space, especially in our domain.

There were several demonstrations that were decidedly more low-tech, involving minimal or in some cases no electronics. Steven Baker presented a collection of resonant dustbins with contact microphones.

The dustbins were arranged in such a way as to allow two performers to face each other for interactive performance.

I enjoyed getting to try out the hand-cranked instruments of the Crank Ensemble:


[Click to enlarge]

Basically, one turns the crank which creates a mechanical loop of sounds based on the particular instrument’s materials. I have seen the Crank Ensemble perform on a few occasions, but never got to play one of the instruments myself.

I also finally got to try out Tom Nunn’s skatch boxes, which I had seen at the Skronkathon as well as “Tuesdays at Toms”.


[Click to enlarge]

The body of the instrument is a cardboard box, and one plays it by running a comb over the various metal and plastic elements attached to the box. I spent a few minutes exploring the sounds and textures running different combs over the elements, including other combs. It was very playable and expressive, I could definitely make use of one of these!

Another variation on the theme of amplified acoustic objects was Cheryl Leonard’s demonstration in which one could play sand, water, wood, and other natural elements:

Returning now to electronics, and a different kind of “elemental music.” CJ Borosque presented her use of analog effects boxes with no formal input. Analog circuits do have some low-level noise, which is what she is using as a source for feedback, resonance, distortion and other effects. Ferrara Brain Pan demonstrated an analog oscillator than can handle very low frequencies (i.e., less than 1Hz!).

There are also several other live-performance electronics demonstrations. Bob Marsh presented the Alesis Air Synth (no longer in production). Performers pass their hand over the domed surface to manipulate sounds. Similar to the tablet, this is a very intuitive and rich interface. Rick Walker demonstrated a new powerful instrument for recording and controlling multiple live loops, with the ability to manipulate rhythm and meter. I look forward to hearing him use it in a full performance soon. Thomas Dimuzio showed a full rig for live electronics performance, that I believe he used at the electronics-oriented concert the following week.

2009 Annual Transbay Skronkathon

It is mid-summer, and so once again the annual Transbay Skronkathon and BBQ comes around, with a full day of experimental and weird music at 21 Grand in Oakland. There are always a few from outside the Bay Area, or who are appearing in this setting for the first time, but overall it is a who’s who of local experimental and avant-guard musicians and familiar faces. We spend the whole day performing and listening to music, and dining on a variety of grilled food items in the neighboring alley.

I arrived at 4PM, which was already three hours into the event. I was just in time to catch most of Respectable Citizen, a duo of Bruce Bennett and Michael Zbyszynski performing live improvisation with keyboard/electronics and saxophone, respectively. The set started with ethereal noisy computer sounds in the background, with the noises increasingly insistent and louder over time, culminating in a defined whistle sound and a wave that became something akin to electrical noise. The electronics were complemented by the saxophone improvisation; there was a moment where the sax and electronics together formed a sound like an emergency siren. Then things became quiet again with the noise growing into an ever louder rumble.

Next was electric-guitar looping performance by George Ludwig. It was very similar to the looping guitar performances I hear annually at the Live Looping Festival in Santa Cruz, with drones and long tones; mostly harmonic, though there was some good clean distortion effects as well.

I made sure to be in for the next group, T.D. Skatchit, featuring Tom Nunn and David Michalak on custom instruments called skatch boxes. I had just seen Nunn and his custom instruments at the “Tuesdays at Toms” performance. This performance featured similar instruments, made primarily of cardboard and performed with combs and other implements. The result is a series of scratches, streches, scrapes, squeaks and other noises, all very musical. With two performances and multiple instruments, harmonies start to form. Even when not looking directly at the performers (which is quite interesting to do), the performance had a very “visual” quality. The overall texture reminded me of the sounds of the woods at night. I could hear scampering mechanical creatures. Although the structure of the music was very static, the performance was very expressive.

The next set was a trio of Jacob Felix Heule (drums), Tony Dryer (double bass) and
Jay Korber (tenor sax). This set qualified as actual “skronking”, with very rapid notes (especially on the drums) and the belting of inharmonic and variable pitch tones on the sax. Lots of details to listen to. But above all, skronking tends to be very loud, so I did end up listening to second part of the set from the alley, where I also had a chance to socialize and check out the barbecue.

However, the loudest set of all was yet to come, and it wasn’t even officially on the program. Someone in a ski mask with a table-saw on an old turntable record player claimed to be the next set Sndrft eeoo, though it turned out he wasn’t. Nonetheless, we were treated to ear-threateningly loud high-pitched noises that sent everyone out into the alley to join those of us already there for conversation and sausages (the official food of choice at the Skronkathon). Outside, the sound was somewhat bearable, and vaguely interesting. Sndrft eeoo and Mike Jacobs did get to play an abbreviated set once the impostor left the stage (much to our collective relief).

Hanuman Zhang described his set as found objects, toy piano, circuit-bent toys
noise, mayhem, and roaring silence. He was introduced by Tom Duff as playing “a big pile of junk” – but a nonetheless musical pile of junk. He started with stones and bass drum, making rhythms. He then moved to to bins and metal objects, all the while maintaining a basic rhythm. He bashed in a large plastic bottle really good. There were also some electronic circuit-bent toys, and a toy piano (acoustic toy piano being an instrument I am quite fond of). As the toys came to the forefront, the rhythm began to break down and the texture more sparse.

From loud skronking and found objects, we then had a very contrasting set from Protea, with Serena Toxicat and thereminist Joey D’Kaye performing ambient electronic music. Sporting a Hello Kitty tunic, Serena Toxicat gave an evocative performance with vocals and dancing . The vocals and theremin both consisted of long tones that followed one another without exactly matching. Overall, there were minor harmonies, etherial textures, gradual changes and a bit of tension.

We then switched back from ambient electronic to skronking (but it is really “skronking”?) with a free-improvisation set by z bug with David Leikam, Zachary Morris, Sheila Bosco and Craig Latta. Once again, lots of fast loud notes, with the bass acting as a third drum set (there were two drum sets in this group), and some performance with a Moog synth. Although the set was very loud at times, there was really a good range with sudden drops in volume where one could here bells and chimes sounding. However, I could not at all hear the vocals. I did like the sudden switch during the performance to a steady disco beat.

Tom Nunn and David Michalak returned as part of RTD3. Overall, the performance was similar to their set the previous tuesday, with Nunn and Michalak performing free improvisation together Ron Heglin on trombone and Doug Carrol on electric cello. However, Nunn’s instrument in this set was quite different. It was a much larger board that he played vertically. It looked a bit like a modernist painting with some elements that seemed derivative of Kandinsky, but it had a very clearly marked eye and geometric shapes. The texture of music was more sparsem and there was a good moment with soft trombone. it sounded like “a radio from the past.” There was a section that sounded vaguely ethnic (in the way that a contemporary western audience might label some music as “ethnic”) and then hit a watery pattern on Nunn’s instrument.

John Hanes and Steve Adams performed “dueling laptops” (and an iPhone). Moments in the music reminded me a bit of one of my favorite Stockhausen recordings, but there were also drums and beats, timbrally rich drones and bowed tones and loops. It reminded me a bit of the “Off-ICMC” concerts (often the more interesting performances) I would hear when I used to attend the computer-music conferences.

I did not get to hear as much of PG13 in detail as I would have liked because I was busy setting up for our upcoming set. The trio consisted of Phillip Greenlief on saxophone, John Shiurba on guitar and Thomas Scandura on drums. It seemed during the introduction that there was some question as to whether they should be described as “1970s rock” or not, but musically they did have a strong driving 4/4 beat with heavy drums and loud guitar. Greenlief also played very rhythmic accented lines on the saxophone that fit with the guitar and drums. So with my only partial listening, it did have a lot of “rock-like” elements, which were welcome, and a good lead in to our own set.

This was our first time performing re-named as Reconnaissance Fly and as a trio rather than a quartet, with myself, Polly Moller (flute, voice, heatsink) and Bill Wolter (guitar, custom electro-mechanical “boat”). We are currently looking for a bassist/composer to round things out.

The set consisted of four pieces based on “spoetry” or poetry found in spam emails – most email spam (or blog-comment spam) is completely worthless text, but occasionally there are very poetic passages that can be used for creative work. I did two pieces setting spoetry to graphical scores in which the performers improvised based on interpretations of graphical elements, and Polly and Bill each did more idiomatic pieces. All the practicing and rehearsing paid off, and the set was quite tight and full of energy, with fun and theatrics – and I’m glad I brought the full keyboard for playing more traditional jazz piano at various spots alongside the more esoteric electronic sounds from the Kaos pad. Probably the most memorable moments were repeated riffs on “Ca-a-na-da-a”, and the rolling jazz bass and guitar in “Emir Scamp Budge”. And it seemed like we had a pretty decent audience.

We were followed by the all-acoustic sfSound group. As an acoustic group with winds, strings and percussion, they have a really rich palatte of textures and timbres. One can hear small percussive phrases emerge from a series of long tones. The winds (Kyle Bruckmann,
Matt Ingalls, Christopher Jones, and John Ingle) sometimes match the percussion (Kjell Nordeson) , sometimes the strings (Alexa Beattie, Monica Scott). The performance was very subtle with lots of dynamic range and empty spots, and quite a contrast to our set with its loud electronic improvisations and theatrics.

sfSound was immediately followed by another powerful accoustic set, featuring Karen Stackpole with her impressive array of gongs, Jen Baker and Ron Heglin on trombones, and Tom Djll on trumpet. An unusual instrumentation, “Brass and Bronze” (as introduced by Tom Duff). The set began with the gongs followed by really soft long notes on the three brass instruments. The gongs resonated as Stackpole moved along their perimeters, producing beautiful long stretched out tones. They formed inharmonic chords anchored by drones on the brass. The texture became less sparse over time with bowing of gong and faster swells on trombone and notes on trumpet. This eventually turned to loud hits and gong strikes, and more expresive phrases.

The final set of the Skronkathon featured Gino Robair and Amy X Neuburg on dueling Blippo Boxes. The Blippo Box is a custom analog synthesizer by Rob Hordijk that features chaotic oscillators and a wide range of non-linear modulation options – I wouldn’t mind having one of these myself. The Blippo Boxes produce constantly modulating sounds that are difficult to control in advance, the performer must react to whatever is produced using his or her best musically instincts. As the boxes can occasionally go unstable, being able to react quickly is key. Fortunately, we have two master musicians whose listening and improvisational instincts can be called upon to handle such situations. The result was a very expressive mixture of machine noise and rumbles, gargles, clicks and chirps – the chaotic sound actually becomes familiar after listening for a few minutes (though in fairness I should say years of listening to such music). And there were many moments where the oscillations of the two boxes seemed surprisingly on sync, with the waveforms and modulations slowing down to the level of musically distinct notes.

And once the Blippo Boxes went silent, this marathon event came to a quiet end.

Weekend Cat Blogging and more: Studio

Luna looks out the window, as the new studio starts to take shape.

We see a side rack here, with a couple of colorful E-MU modules, and a couple of classic Yamaha FM modules. Near the window is a non-electronic instrument, a large bell made from a spent CO2 cartridge.

Of course, the main attraction is Luna with her perfectly groomed fur and sharp pose. This might be one of my favorite photos of her to date in our new home.


We saw Luna playing hide-and-seek in the studio last weekend. And that is the theme of this weekend's Bad Kitty Cats Festival of Chaos, hosted this weekend by Chandra & Samantha at New Tuxedo Gang Hideout.

Weekend Cat Blogging #143 is being hosted this weekend Meowza at Mind of Mog.

The Carnival of the Cats is happening this Sunday at Grace & Kittens. And of course the Friday Ark #180 is at the modulator.
