CCRMA Modulations at SOMArts

A few weeks I go, I attended CCRMA Modulations 2011, an evening of live electronic music and sound installations by CCRMA (the Center for Computer Research in Music and Acoustics at Stanford) and special guests at SOMArts in San Francisco. The event was an eight-hour marathon, though I only stayed for about half the time, seeing many of the installations and most of the live-music performances.

The first part of the evening featured sound sculptures from Trimpin and his students at CCRMA. This particular project, the “Boom Boom Record Player” by Jiffer Harriman stuck with me.

The output from the record player is used to drive the electromechanical instruments on the right. I thought the instruments were well crafted – but I thought it was particularly fitting to have a classic Earth Wind and Fire LP on the record player.

Trimpin’s offering featured coin-operated robotic percussion where the drums included just about every model of Apple notebook computer going back to an early PowerBook (and even earlier as I think I espied an Apple IIc).

The live-music portion of the evening with Tweet Dreams by Luke Dahl and Carr Wilkerson. Audience members with Twitter access were encouraged to live-tweet messages to a specific hashtag #modulations. The messages were then analyzed in real time and the data used to affect the music. As I was planning to live tweet from this event anyway via iPhone, I was ready to participate. Of course, inviting audience participation like this is a risky proposition for the artists, as one cannot control what people may say. I will freely admit I can be a bit snarky at times and it came out in some of my tweets. The music was relatively benign, with very harmonic runs of notes – and I exhorted them to “give me something harsh and noisy”. Inspired by another participant, I also quoted lines from the infamous “More Cowbell!” skit from Saturday Night Live, much to the delight of some in the audience. The main changes in the music seemed to be in density, rhythm and some melodic structure, but all within boundaries that kept the sound relatively harmonic and “pleasant.” I would have personally liked to see (as I suggested via Twitter), more complex music, with some noisy elements and more dramatic changes. But the interaction with the music and and the audience was a lot of fun.

The next piece, Sferic by Katharine Hawthorne, featured dance and electronics. It was described as “using radio and movement improvisation to explore the body as an antenna.” The dancers, dressed in black outfits with painted patterns, began the movement to a stream of radio static. The motions were relatively minimalist, and sometimes seemed strained. Gestures included outstretched arms and fingers pointing, with Hawthorne walking slowly as her dance partner Luke Taylor ran more quickly. Rich, harmonic music entered from the rear channels of the hall, and dancers moved to being flat on the ground. The static noise returned, but more crackly with other radio-tuning sounds, then it became a low rumble. The dancers seemed to be trying very hard to get up. Then they started pointing. The music became more anxious, with low percussive elements. The dance became more energetic and active as the piece came to a close.

This was followed by Fernando Lopez-Lezcano performing Dinosaur Skin (Piel de Dinosaurio) a piece for multi-channel sound diffusion, an analog synthesizer and custom computer software. The centerpiece was a custom analog synthesizer “El Dinosaur” that Lopez-Lezcano build from scratch in 1981.

The instrument is monophonic (but like most analog synthesizers, a very rich monophonic), multiplied for the purposes of the performance by audio processing in external software and hardware. The music started very subtly, with sounds like galloping in the distance. The sounds grew high in pitch, then descended and moved across the room – the sense of space in the multichannel presentation was quite strong. More lines of sound emerged, with extreme variations in the pitch, low and high. The timbre, continually changing, grew more liquidy over time, with more complex motion and rotation of elements in the sound space. Then it became more dry and machine like. There was an exceptionally loud burst of sound followed by a series of loud whistles on top of low buzzing. The sounds slowed down and became more percussive (I was reminded as I often am with sounds like this of Stockhausen’s Kontakte (II)). Then another series of harsher whistles and bursts of sound. One sound in particular started the resonant quite strongly in the room. Overall, the sound became steady but inharmonic – the timbre becoming more filtered and “analog-like”.

The final performance in this section of the evening featured Wobbly (aka Jon Leidecker) as a guest artist presenting More Animals, a “hybrid electronic / concrete work” that combined manipulated field records of animals with synthesized sounds. As a result, the piece was filled with sounds that either were actual animals or reminiscent of animal sounds freely mixed. The piece opened with pizzicato glissandi on strings, which became more wailing and plaintive over time. I heard sounds that either were whales and cats, or models of whales and cats. Behind this sounds, pure sine tones emerged and then watery synthesized tones. A series of granular sounds emerged, some of which reminded me of human moaning. The eerie and watery soundscape that grew from these elements was rich and immersive. After a while, there was a sudden abrupt change followed by violent ripping sounds, followed by more natural elements, such as water and bird whistles. These natural elements were blended with AM modulation which sounded a bit like a helicopter. Another abrupt change led to more animal sounds with eerie howling and wind, a strange resonant forest. Gradually the sound moved from natural to more technological with “sci fi” elements, such as descending electrical noises. Another sudden change brought a rhythmic percussion pattern, slow and steady, a latin “3+2+2” with electronic flourishes. Then it stopped, and restarted and grew, with previous elements from the piece becoming part of the rhythm.


After an intermission, the seats were cleared from the hall and the music resumed in a more techno dance-club style and atmosphere, with beat-based electronic music and visuals. Guest artists Sutekh and Nate Boyce opened with Bands of Noise in Four Directions & All Combinations (after Sol LeWitt). Glitchy bursts of noise resounded from the speakers while the screens showed mesmerizing geometric animations that did indeed remind me a bit of Sol LeWitt (you can see some examples of his work in previous posts).

Later in the evening Luke Dahl returned for a solo electronic set. It began calmly with minor chords processed through rhythmic delays, backed by very urban poster-like graphics. Behind this rhythmic motif, filtered percussion and bass sounds emerged, coalescing into a steady house pattern, with stable harmony and undulating filtered timbres. At times the music seemed to reach back beyond house and invoke late 1970s and early 1980s disco elements. Just at it was easy to get lost listening to Wobbly’s environmentally-inspired soundscapes, I was able to become immersed in the rhythms and timbres of this particular style. The graphics showed close-ups of analog synthesizers – I am pretty sure at least some of the images were of a Minimoog. I did find out that these images were independent of the musical performance, and thus we were not looking at instruments being used. I liked hearing Luke’s set in the context of the pieces earlier in the evening, the transition from the multi-channel soundscapes to the glitchy noise and to the house-music and dance elements.

I was unfortunately not able to stay for the remaining sets. But overall it was a good and very full evening of music and technology.

Zimoun and Jim Haynes at Swissnex

In mid-January, I had the opportunity to see a performance by Swiss artist and instrument-maker Zimoun and local artist Jim Haynes at Swissnex here in San Francisco.

Swissnex is tucked away on quiet block in a “neutral zone” between the FInancial District, Chinatown and North Beach (an area I enjoy passing through on some of my long walks). The space is very minimal and stark white, with bits of the structural architecture and industrial quality of the building present. Within this space, a large array of music-making machinery was set up. One one side was Zimoun’s very minimal instrumentation, and on the other the chaotic array of gear and elements that would make up Haynes’ performance.

Zimoun’s instrument was incredibly simple, a series of cardboard boxes on top of which were mounted ping-pong balls on motorized arms. The boxes served as resonant chambers for the excitation of the ping-ping balls.


[Click to enlarge.]

The performance unfolded as simply as the instrument itself. First, one of the five units began to vibrate, producing a low rumbling sound. Gradually the other ball+motor+box elements entered the mix, producing an odd harmony of machine noises. Out of this combination, I heard a higher-pitched metallic sound. I am not sure if this came directly from the machinery of the instrument, or was an acoustic artifact from the interaction of the different sounds. That is one of the interesting things about having such a minimal concept behind a piece, it allows one to focus on the output and explore minute details that would often be lost in a more complex performance. The piece continued as continuous sound, without much in the way of change or development, for about twenty minutes. The combination of the sound and visual environment allowed for a few minutes of peaceful detachment and I was able to experience it purely as signal and image processing without social context.

Jim Haynes’ performance was a sharp contrast to Zimoun, both aurally and visually. His table was covered with a diverse array of audio devices and lab equipment.

[Click to enlarge.]

At first, I took the metal column and rings to be a custom-made theremin of sorts before realizing that it was the rings and tower familiar from countless science classes.

After an initial burst of loud noise and feedback (which reassuringly let us all know that “yes, this thing is on”), the sound unfolded as an exploration of traditional elements, notably fire, air and earth. He opened with fire, specifically from the flame of a lit candle. He latter added sand, which poured from a bottle he placed on the metallic rings so that the sand could gradually fall out onto a contact microphone. While Zimoun’s performance invited detachment, Haynes’ required close attention. Many of the sounds that emerged seem closely related to the elemental sources: from the fire a series of crackling sounds and wind sounds from the excited air, and from the sand a sea of granular noises that could at times seem like liquid. But there were other sounds as well, the sound of ambient radio static, something akin to vinyl noise, a high-pitched shaking sound, and metallic rattling. Whether these were directly from the fire and sand or from the BOSS Dr. Sample and associated effects boxes is unclear.

This performance was in many ways a preview for Zimoun’s exhibition at the Gray Area Foundation for the Arts (GAFFTA) which opened a few days later. That exhibition is still ongoing and will close on on February 22nd. Follow the link for more details.

Googlish translation from matrixsynth:

The other Diego had domestic problems that will prevent you bring your Spanish guitar, so you will be forced to play with this wild animal.

And another picture from amstrad on flickr, featuring Kiska:

Finally, an update from c+c via the comments on matrixsynth:

ust a brief explanation of what was going on here… This was published a couple of days before our first Corrientazo, a concert featuring many musicians using compact synthesizers and DIY stuff. So we were announcing that Diego, from Befaco, was going to play with a prototype of their new Slicer / 8 step sequencer, to be released later this month (more info soon!).

Then I heard news from Amstrad that he was no longer going to play spanish guitar + MFB 522 in the concert, because the cat ate the guitar! So he brought his DIY modular, from the Befaco workshops, instead; and played it via MIDI from his iPhone!”

I would be curious to hear the iPhone + Befaco performance…

Omega Sound Fix, Alfa Art Gallery

Today we look back the Omega Sound Fix Festival, which took place at the Alfa Art Gallery in New Brunswick, New Jersey. The festival spanned two days, Saturday, November 20 and Sunday, November 21, and I was myself scheduled to perform on the second night. (You can read an earlier article about my preparations for the event here.)

As with other events this year, I was live tweeting during the performance @catsynth, using the tag #omegasoundfix. Additionally, PAS has posted videos from the first night of the event, several of which are included below.

After a brief trip to lower Manhattan on Saturday, I headed across the river via the Lincoln Tunnel (which the iPhone assured me had the least traffic of any crossing) and south on the New Jersey Turnpike towards New Brunswick. It was comforting to finally arrive at Alfa Art Gallery after the long trip and come in out of the cold air to the abstract electronic sounds. I arrived in time to hear the second half of Richard Lainhart’s set (I wish I had arrived in time to hear the whole thing). You can see part of Lainhart’s performance below:

Richard Lainhart live at Alfa Art Gallery (Part II) for the Omega Sound Fix Festival from PAS on Vimeo.

I had not arrived in time to hear Lainhart’s introduction in which he explained that piece was by the renowned 20th Century composer Oliver Messaien – a 1937 piece Oraison that was was one of the early pieces written purely for electronic instruments. It was later adapted for acoustic instruments as part of Messaien’s “Quartet for the End of Time”, composed while he was in a German prisoner-of-war camp in 1941. Lainhart’s arrangement of the piece uses the Haken Continuum with a Buchla synthesizer. The music starts out very quiet and melancholy, like a mournful piece of acoustic chamber music. But one can hear the timbral details, suble pitch changes and effects that make it unmistakably electronic. Every so often, there is strong feedback in the sound, but it remains very expressive within the context of the piece. The harmonies move between minor and very anxious augmented. It feels very much like piece of music for a dramatic film, set in forlorn ruins or a desert approaching dusk.

Lainhart then joined Philippe Petit for the next set. I would characterize Petit’s performance as “virtuosic experimental turntable”, as that was the primary instrument he was using (along with a laptop) to generate his sounds that were at once very natural and very constructed. The set began with Lainhart playing long bowed tones on the vibraphone set again Petit’s liquidy granular sounds, scratches, low rumbles and anxious harmonies. There was a strong contrast between the more ethereal and natural timbres, and the lower-frequency and louder machine noises. Petit’s sounds moved from more natural and machine towards snippets from other recordings with bits of distorted harmony, and urban city-like environments. It then changes over to turntable effects, pops and skips and speed changes, and gets noiser and more agressive. Lainhart’s bowed vibraphone provides a constant dreamlike quality against Petit’s changing textures.

At some point during the set, the duo were joined by a guitarist to form a trio. [Note if anyone can provide me the guitarist’s name, please let me know!] The trio with guitar began scratch and percussive, but became more tonal over time. There is a section which I referred to as the “thud march”, which electrical pops forming a march-like rhythm with other turntable effects filling in the space in between. The rhythm breaks apart after while, with the electronic pops continuing in a more chaotic pattern, and scratching and percussive effects on the guitar providing a counterpoint. Quiet inharmonic synthesizer pads can be heard in the background. The set drew to a large close, starting with a quiet turntable solo and then into a big finish, with loud howling wind-like sounds, and dark harmonies.

They were followed by PAS (Post Abortion Stress). Petit remained on stage and joined regular group members Michael Durek, Robert L Pepper and John “Vomit” Worthley and guest saxophonist Dave Tamura.

The set began with a very simple pentatonic sequence. On top of this, Worthley played a bowed waterphone waterphone, and Durek soon joined on thermin with a melodic line. Tamura’s saxophone provided a strong counterpoint to the other elements, alternating between very expressive jazz-like lines and a “skronking”. There were moments where the saxophone and thermin seemed to respond to each other, melodically and harmonically. At some point, the original pentatonic pattern cut out, and the music centered around saxophone, theremin and electronic violin. This was followed by a purely electronic section with dark analog sounds and driving electronic drums. Pepper repeatedly slammed his electronic violin against the table, while Tamura played fast runs on the saxophone. Another interesting moment was Pepper using a standard fishing rod as an instrument (perhaps the first time I have seen that), set against synthesizers, guitar and saxophone. Gradually the music gets louder and more insistent, with driving percussive guitar, loud saxophone, and synthesizer sweeps, howls and sound effects in the background. Below is a video of PAS’ entire performance.

The Sunday program began with blithe (doll). The performance combined acoustic drums as a foundation with live electronics and voice. I particularly liked the combination of loungy Latin rhythm and harmony in one piece with eerie electronic sounds and Phrygian vocal melodies that permeated much of the set. There were sections that were more “spacelike” with analog square waves and loud hits. Overall, the slow rhythms and melodies were reminiscent of goth or darker electronic club music.


[Click image to enlarge.]

This was a fun set to watch and listen too, and the band drew a relatively large crowd. I guess that should be surprising given that the band is local, and husband-and-wife duo of James and Lisa Woodley were well known from the previous band.

Blithe (doll) was followed by Borne (aka Scott Vizioli). He created a large dramatic and very visual soundscapes. Although his sounds included ambient, environmental and noise-based material, there was also a somewhat unsettling minor harmony that seemed to be just under the surface. Nonetheless the overall sound it was quite meditative, and easy to get lost in the soundspace. Over time, a beat emerged, very sparse and minimalist with metallic sounds. It gradually became stronger and more drum-like, with ethereal bell sounds in the background. I also recalled a single sample of a dishwasher (or something that sounded like a dishwasher) towards the end.

Next up was Octant, which could be described as a band consisting of one human and several robots. The electromechanical robots play acoustic instruments (drums, etc.) while the human member of the band, Matthew Steinke performs on lead vocals.

This was a unique set to watch. My focus was definitely on the robotic performance, but I was also listening to the music itself, which reminded of 1960s British rock with lots of chromatic chord changes. (@catsynth It’s not every day I see retro rock music performed by robots #omegasoundfix ). In order to get a rock rhythm feel, the timing among the robots needs to be well controlled – too much jitter or drift between machines and the musical quality is lost. Octant seems to have that down from a musical and technological perspective. Among the individual songs were “Bowl of Blood”, and another that was introduced by Steinke as being a “song about my cat.”


[Click image to enlarge.]
Octant was followed by Ezekiel Honig. As stated in the program notes, “He concentrates on his idiosyncratic brand of emotively warm electronic-acoustic music.” The set began with sounds that evoked water as well as machinery. I was able to hear that we was making extensive use of looping, although as he states he is “using the loop as more of a tool than a rule” and elements come and go freely outside the context of strict looping. A strong heartbeat sound emerged, and then later other elements joined to form a calm rolling pattern. At one point a strong major 7th harmony emerged. The beating changed sublty over time, as did the implied harmonies, which became more minor. Towards the end, the sounds seemed to focus on voices in the distance and other evidence of everyday human activity.

I had to begin setting up for my set after this, but I was able to part of Trinitron, the musical project of local artist Mark Weinberg. More so than Honig’s set, Trinitron’s performance was very focused on looping of processed electric guitar. Weinberg sat with his guitar in the middle of a circle of candles, and began to layer different lines and effects on top of one another. The resulting sounds from were alternately harmonic and gritty or noisy. Overall, his performance had an ambient dream-like quality to it.

Then it was time for me to play. I started the set with one of the “Big Band Remotes”, old radio broadcasts of big band shows made in the 1930s and 1940s. In particular, I used a recording of Count Basie and the Blue Note in Chicago, under the control of the monome so that I could start, stop and jump to different sections at will. I immediately segued from the final note to the Chinese prayer bowl and a similar metallic resonance on the Evolver synthesizer. After a while, I attempted to add the Smule Ocarina to the mix, though attempting to induce feedback from the speakers was a little more unstable than I had hoped. The second piece involved live sampling and looping of several of my Indian and Chinese folk instruments, including the newly acquired dotara, the gopichand, and Chinese temple blocks. Once again, this was under control of the monome. The piece transitioned to more electronic sounds, otherworldly crashing waves and loud resonances, and into a meditative solo using a guzheng app on the iPad. You can see a video of the first two pieces below:

I then performed 月伸1, the video piece featuring Luna that I did at the Quickening Moon concert in February. In this instance, I did not have the Octave CAT synthesizer, but instead used the Smule Magic Fiddle and Korg iMS-20 on the iPad as the main electronic instruments, along with the Bebot app, a simple synthesizer on the laptop controlled by the monome, and the Evolver. I liked the new iPad apps for improvising against the video, it gave it a different musical quality from the premiere performance, though not as different as one might suspect. The video projection was a challenge – it covered the entire back wall, and I found myself standing “inside” the images, sometimes next to a gigantic projection of Luna. The effect of the projection against the artwork was also quite interesting visually. You can see this performance in the video below:

My performance was the last of the evening, and of the festival. Overall, I thought it was a great experience, both as a performer and audience-member. Thanks to Michael Durek and Mark Weinberg for organizing this event, and to the Alfa Art Gallery for hosting.

Solo Electronic Set and Johnston-Nelson-Wright Trio at Luggage Store Gallery, September 16

[Note: for Weekend Cat Blogging, please scroll down or click here.]

Today we look back at my solo performance at the Luggage Store Gallery in San Francisco two weeks ago. This was part of the regular Outsound music series every Thursday, and on this night featured two very contrasting sets: my solo electronic work, and then an acoustic horn trio.

We being with a view of the setup:

My solo rig has slowly turned into a table from an Apple store, with an iPhone, iPad, and MacBook all in use. At the same time, I continue to blend old and new technology with the presence of the traditional Indian instruments, such as the ektar and gopichand, and Chinese instruments. I set up the monomer to mostly face the audience and provide interesting displays on the grid, unless I specifically needed to interact with it.

[Click image to enlarge]

From my perspective, as well as a couple of people I talked to in the audience, the most successful piece was the new string-centric piece that combined the guzheng model on the iPad with live sampling of the ektar and gopichand. This piece mixed traditional instruments of two cultures with advanced technology. In addition to the iPad, this piece used the mlr application with the monome for sample playback and looping. Most importantly, however, was how it came together musically with the harmonies and timbres of the instruments standing on their own to create a meditative soundscape.

The other piece that worked well was my update of the meditation with prayer bowl and DSI evolver, which also incorporated the Smule Ocarina on the iPhone. I used the feedback technique again where the iPhone is placed in front of a speaker and starts to play itself. Here is a video excerpt:

Overall, it was a good performance and provided an opportunity to try out new things. It was nowhere near as tight and polished as my set at the Quickening Moon Concert back in February, though (or as well attended).

I was followed on the program by the horn trio of Darren Johnston, Matt Nelson, and Cory Wright. Their improvised music moved back and forth freely between rhythmic avant-garde jazz, long drones and all-out skronking.

Although it was a completely different instrumentation and format, there were a few similarities between the trio and my set, particularly towards the beginning. The opened with a series of complex rhythms with pauses and odd time relations that reminded me a bit of the piece I did with the monome+mlr. Every so often, the rhythms came together into a uniform pattern and then into long notes that formed perfect intervals or occasional consonances with thirds. Then the drone broke apart. On the opposite end, there were noise elements, especially on the trumpet and more atonal harmonies. At one point, the sound was reduced to very soft breath noises, followed by a swell with staccato notes and warbles, getting ever busier and louder.

The next segment began with solo muted trumpet. While listening, I was thinking how muted trumpet always sounds “jazzy” no matter the style of music being played. The jazz feel was sustained as the other performers came in, building a texture that was both elaborate and nostalgic. The jazz feel gave way to more percussive sounds, such as rubbing the headjoint of the soxophone on the body of the instruments. The mutes themselves became percussion instruments, as did a beer bottle. The percussion sounds were loud and resonant, set against clarinet and saxophone headjoint.

The final piece opened with a nice strong baritone saxophone solo. At the same time, the other performers began dropping and throwing objects on the ground. Then everyone came in again on horns with fast and loud notes. The saxophone in particular kept the percussive quality going.

It was a short set, but overall quite good and kept my attention throughout.
