CatSynth videos: Cats react to iPhone Cat Piano

Today I specifically wanted to post some cat-and-iphone-music videos. While these don’t quite rise to the level of iggy investigating the iPad, they do make use of the popular “cat piano” app for iPhone.

From luke255 on YouTube:


“My cat Dennis has an interesting conversation with my iPhone!”

And another, from amb0 on YouTube:

The black cat in this video looks a bit like Luna.

I do of course have this particular iPhone app, and have even used it in some shows. Luna has shown very little interest in it, however. She is clearly jaded from gadgets making strange sounds (even cat-like sounds)

Preparing for Thursday’s performance: Luna’s video

Over the last few days, I have largely been absorbed by preparations for my next performance. This one includes a more ambitious element, a 10-minute video entitled 月焞1 featuring clips of Luna as well as abstract elements reminiscent of experimental filmmakers such as Stanley Brakhage or Gerhard Richter. The video will serve as a backdrop for live electronic improvisation – it is mostly silent, though I did include some sound at various points so the audience could hear Luna’s voice.

Here are a few example frames from the video:



Some of the video clips of Luna were featured here on CatSynth in the past, including her chattering video, or playing with her blue fish toy. The abstract elements were done is a software package called Processing, a programming language for images, animation and interactions.

Musically, I will plan to focus on a mixture of the Evolver and the Octave CAT synthesizers, along with software on the iPhone and laptop. Indeed, this is the first time I will be using the CAT live, mostly because I am reluctant to move it too often.

Of course, this will only cover about one third of the full performance, so I will be drawing from my repertoire of electroacoustic improvisation to round out the remainder of the time. Although I reuse elements, there is always something new to discover in them.

Full Moon Concert Series: Quickening Moon
Thursday, February 25, 8PM
Luggage Store Gallery, 1007 Market Street @ 6th Street, San Francisco.

The Full Moon Concert Series is an experimental music series offered by Outsound Presents, in partnership with the Luggage Store Gallery. Each concert explores the traditional lore of the Full Moon, and in January, the second annual “Quickening Moon” will feature new music springing to life. First up will be Amar Chaudhary in a solo electronica set (collaborating with his wonder-cat, Luna), followed by the world premiere of a new work for twelve improvisers by Polly Moller, entitled Genesis.

NAMM iPhone App

I am expecting to see several iPhone applications at NAMM, but this one is particularly handy as I start my tour:

It can be used to map the convention halls, search vendors by name, category and location, and “bookmark” them so you can see on the map where you might actually want to go (and thus avoid getting lost in the endless sea of guitars in the middle of the convention center). I was able to quickly put in some of my own priorities as well as those I have followed on matrixsynth and elsewhere.

Pmocatat Ensemble and Chorus, and Weller-Borosque Duo

Last Thursday night, the Pmocatat Ensemble performed again at the Luggage Store Gallery. Pmocatat (pronounced “Moe Ka Tatt”, the “p” is silent) stands for “pre-recorded music on CDs and tapes and things”. The members of ensemble pre-record acoustic material (instruments, voice, environmental sounds, etc.) according to compositional instructions, and then during the performance, improvise with these pre-recorded sounds using standard playback controls: play, pause, fast-forward, rewind, and speed controls. Devices used for playback included CD players, cassette tape players, and iPods/iPhones. This performance featured Matt Davignon, Amar Chaudhary, Suki O’kane, Michael Zelner, Rent Romus and Edward Schocker. It was billed as the “Pmocatat Ensemble and Chorus” as many of the pieces featured vocal material.

We opened with a sparse piece, with single-syllable words entering periodically to perform collaborative nonsense phrases. There was a lot of open space between the words, which was filled in with droning instruments later in the piece. This was followed by a free-improvisation with pre-recorded woodwinds, mallet percussion and bell sounds. The result was an expressive performance with rich textures and complex rhythms composed articulated notes from the different instruments.

My composition contribution was a piece with a graphical score which called for vocal sounds, instrumental and vocal drones, and animal sounds. It for this piece that I recorded clips of Luna last week, and thus she made her “debut” in a new-music concert. Her meows were set against moderately long vocal sounds that arbitrarily “cut off”, followed by a series of very short sounds to represent the tiny scratches in the graphical element. Here, we heard Luna’s clicking sounds that she makes when hunting. For the longer sounds, her purrs were set against various drones. I think was received well, judging by the looks of delight and amusement from various members of audience.

The graphical piece was followed by an interpretation of Pauline Oliveros’ Form Unknown Silences. The sparse texture, with a variety of short sounds interrupting periods of silence, had both a playful and meditative quality. This was followed by a brand new piece featuring guitar sounds set against percussion. The percussion was really following the guitar sounds, with the pa

This being a holiday show, we of course had to conclude with a holiday offering. In this case, it was a rendition of the classic “O Christmas Tree”, with pre-recorded versions of the song sung very slowly, and played back even more slowly and asynchronously, with gaps, pauses and changes in playback speed overtime growing more complex until the artifacts overtook the original.


The Pmocatat Ensemble was preceded by a duo of Ellen Weller and CJ Borosque. The set opened with an atonal “call to prayer” of Weller on a shofar and Borosque on trumpet. The remainder of the set unfolded as an interplay with Weller’s wind instrument and Borosque’s noise synthesizers (and trumpet). Among her instruments was an experimental box with chaotic oscillators and filters – I acquired one of these a few weeks ago but she has gained significantly more proficiency than I have. There were moments with fast saxophone phrases against the synths, and others with Weller’s exceptionally noisy and agressive flute sounds against very finely articulated synth noise. Other moments included undulating unstable waves, a snake charmer flute, and a variety of acoustic and electronic squeaks. The were moments when the music became quite trancelike even as it remained loud and noisy.

Expanded Strangelet at oakuff

Last night I performed with Expanded Strangelet at the Oakland Underground Film Festival. The Expanded Strangelet was described as “Lucio Menagon’s peripatetic ensemble with Suki O’kane, Michael Zellner, Jonathan Segel, John Hanes, Amar Chaudhary, and Allen Whitman.”

This was a combined “music jam” and “projectionist jam”, with several improvised video and film projections on the screen, a free-form piece that followed the more formal screenings earlier in the evening. The screen was filled with several changing images projected from different angles:

It was particularly interesting in the context of the theatre itself. This was one of those classic cavernous movie theaters with stylized art-deco details, but with very contemporary abstract lighting in deep blues, reds and violets, as can be seen on the right side of the image above.

It was in this context that we set up on the floor of the theater and made music. Basically, the performance was a collection of bleeps and bloops, noises, glitches, loops, crashes and snippets of melody and harmony here and there. Nonetheless, it was all musically done with phrasing and dynamics, loosely “conducted” with ongoing whispered directions from Suki O’kane.

In order to keep things light, I bright a very small setup, consisting of red Korg Kaos Pad, an iPhone now loaded with multiple software synthesizers, a circuit-bend instrument with photovoltaic modulation, along with a small mixer and amplifier.

As expected, it was difficult to pay attention to the screen during the performance, while attempting to manage the instruments and listen to the other performers. Fortunately, I did get to see the first half of the projectionist jam with another group providing the music: POD BLOTZ (Suzy Poling) and lazyboy (Bruce Anderson, Dale Sophiea and Gregory Hagan). The combination of images, sounds and environment combining old and new elements, noises and images, was quite captivating.

I would also be remiss if I didn’t mention the beer from Linden Street Brewery. I particularly liked the stout.

Moe!kestra! “End of an Error” at Cellspace

Last night I attended the latest performance of the Moe!kestra! at Cellspace.

“Imagine a man playing an orchestra as though it were a percussion instrument, and you might get some idea of the Moe!Kestra!”. Indeed the performance was in many ways a percussion piece even though the ensemble was almost entirely string instruments: violins, violas, electric guitars, and upright basses. All led by Moe! Staiano.

A Moe!kestra! often includes many familiar musicians. Frequent collaborators Bill Wolter and Clyde Niesen played guitar and upright bass, respectively. Suki O’kane (percussion) and Moe! were both participants in the July Flip Quartet performance. Marielle Jakobsen was part of the Blessing Moon concert that we reviewed here at CatSynth.

The piece being performed was “End of an Error”, inspired by the date January 20, 2009, a date that many of us were highly anticipating, both for its beginning and for the great national embarrassment that it (at least in a formal sense) ended.

The music started out with series of percussive notes on the basses. Soon the violin and viola sections joined in, not on their regular instruments, but instead playing “switches”, i.e., cut sticks that they shook vigorously. An “out of phase” rhythm emerged between the basses and switches, may two notes from the former followed by a splattering of air sounds from the other.

Eventually the other instruments, the guitars, the percussionists and the actual violins/violas entered with more of the percussive notes, and the music became louder and denser. At some point, with all the instruments playing, the texture changed dramatically to something more akin to a “rock orchestra” or a film soundtrack. The pitched material was tonal with lots of familiar chords, but what I call “tense tonality” that one hears in films, and behind it the rhythm of a conventional drum kit from the percussionists. I can’t pin point exactly when the texture and style changed, but it was a sharp contrast.

There were several such changes throughout the performance. Things grew to a crescendo, then “crashed”, with everyone playing long extended tones, forming an atonal drone. After a subsequent swell, there was another “film-like” element with string glissandi. Other moments of note included the tossing of an empty water cooler by Moe! over the heads of the violists. No one was hurt, and it landed a perfect hit in between the other instrumental rhythms.

There was a really thick drone of all seven guitarists playing slides out of sync. The guitarists also closed the performance with a series of repeating flange/chorus tones that gradually came to a stop.


The Moe!kestra performance actually did not begin until 9:30 (despite the announcements suggesting 8PM as the start). We were treated a Sun Ra tribute, featuring videos set to music from The Arkestra. The video included clips of Sun Ra and animations with pseudo-Hebrew lettering and odd vaguely extraterrestial elements, presumably from some of his films. But there were also many other unrelated elements including numerous anime scenes – there was one anime in which all the characters seemed to be playing keytars while doing battle with mechs; martial-arts comedies, a James Bond film (probably Diamonds Are Forever); and a transgendered singer walking down the street and then being transported to another dimension with a Sumo wrestler and bizarre Asian puppet characters. Four of us started playing iPhone Scrabble instead. It has a multi-player mode where one can pass the phone around in a circle and each player takes turns with their own tile set. Highly recommended as a way to pass the time.

room: PIPES

On Sunday, I attended the room: PIPES featuring Polly Moller, Pamela Z and Jane Rigler. The Room chambre series, hosted an produced by Pamela Z, take place in the Royce Gallery, an “intimate performance gallery” in the Mission District of San Francisco. The room: PIPES performance featured performances that incorporated flutes.

Before the start of the performance, we were treated to a welcome by “Ellie”, the freight elevator in the building that houses the Royce Gallery. While some music purists might be appalled to have a freight elevator included in a performance, I found it quite charming to incorporate an element of the industrial setting.

Polly Moller presented a new work, Three of Swords. The performance included an arrangement of Tarot cards, a timer and a series of candles to mark sections of the piece. In each selection, a card was drawn, and the music was an improvisation based on that card. The music focused on extended flute techniques; for example, the first draw led to an improvisation with the head of a bass flute using microtones, overblowing, whistles, clicks and other inspiring sounds. The one section of the performance that stood apart from the others was the drawing of the Three of Swords, illustrated to the right, which launched a very detailed but very expressive description of the human heart.

Pamela Z‘s playful and energetic performance did not feature flutes, but instead focus on voice. It began with live looping of tonal and harmonic singing (look up “live looping” here on CatSynth for a primer if you’re not familiar with the technique), and gradually moved to more extended vocal techniques, including clicks, screeches (with electronic processing), whispers, etc. The video in the background displayed an interior of an old industrial or loft space, empty except for a trunk that appeared and disappeared at various times. Sometimes it was open, to reveal drawers and messy clothes.

Jane Rigler opened her set with a virtuosic flute and electronics piece and the welcoming statement “Do not fear the microphone and piccolo.” She then performed her piece A la pintura, inspired by Robert Motherwell’s paintings, which were in turn a response to Spanish poet Rafael Alberti’s poems celebrating painting. Motherwell’s paintings, both as stills and as animations, were projected during the performance, and there were also moments where text was projected, presumably excerpts from Alberti’s poems. Motherwell’s paintings are quite abstract, focusing on textual elements and geometry. To have these images along with strong flute-and-electronics music (a favorite instrumental combination of mine) was a treat.

The performance concluded with a trio improvisation of all three performers. In addition to the flutes and voice, Polly Moller broke out her “tone nut” (doughnut-shaped wind instrument), and Pamela Z played the popular Ocarina iPhone instrument. It’s always interesting to hear how such disparate musicians play off of one another, and this group improvisation could have kept going on for a bit longer…
