In Tandem with Max Mathews, Aaron Koblin, and Daniel Massey

Last Friday I attended a talk featuring Max Matthews and a new conceptual work by local artists as the Gray Area Foundation for the Arts (GAFFTA). GAFFTA is an intriguing new organization and space for the intersection art, design, sound, and technology. They are “dedicated to building social consciousness through digital culture.”

I had last seen Max Mathews, considered by many to be the “father” of computer music, at an 80th birthday tribute at the Computer History Museum in 2007, and before that delivering the keynote address at ICMC 2006. It is great to see him still going strong and engaged with technology and supporting others’ creative work. His talk primarily focused on his work at Bell Labs, and in particular the history and technologies surrounding his 1962 computer rendition of the song “Daisy Bell” (aka “Bicycle Built for Two”). It was an early example of physical modeling synthesis, where sections of the vocal tract were modeled as tubes, and sound generated directly from physics equations. His version of the song was popularized in the film 2001: A Space Odyssey, although Mathews revealed that the version Kubrick used in the film was not his recording. He also presented another famous example of computer-generated vocals, a performance of the “Queen of the Night” aria from Mozart’s The Magic Flute. This piece used formant synthesis in which focus on recreating spectral characteristics of the sounds (i.e., the formants that characterize vowel sounds) without necessarily modeling the physical processes that allow humans to create those sounds. The voice is quite compelling (if a bit dated), and demonstrates that the most realistic sounds are not necessarily those generated from physical models.

Mathews’ presentation of “Daisy Bell” served as an introduction for a new project “Bicycle Built for 2000” by Aaron Koblin and Daniel Massey. Koblin has been working on a series of conceptual pieces that utilize the Amazon Mechanical Turk, a framework for harnessing human intelligence to solve large problems. There are some things that humans are quite efficient at and computers are very poor at, such as recognizing distorted text (think of the CAPCHA codes that we all deal with on websites, including here at CatSynth). The Amazon Mechanical Turk, which derives its name from an 19th century hoax where a supposedly mechanical chess-playing machine turned out to be a human hidden inside a box, provides a framework and API for defining tasks to be solved by humans, recruiting people to work on them, and then compensating them for their efforts according to a fixed budget. One of Koblin’s pieces provides the instruction to “draw a sheep” for a few cents. He then collected the resulting drawings of various sheep (and non-sheep) from around the world and compiled them into a larger mosaic work, The Sheep Market. You can see the overall mosaic as well as click on individual sheep and even see an animation of how they were drawn by the individual contributors.

For “Bicycle Build for 2000”, Koblin collaborated with Daniel Massey on a work that focused on sound and music. The Max Matthews rendition of Daisy Bell was decomposed in a sound segments no longer than one syllable, and for each segment an Amazon Mechanical Turk task was created for someone to sing back the sound. Koblin and Massey then reassembled the sounds to re-create the song as sung by the participants. The initial version, in which only one singer was used for each component, was almost unrecognizable, though quite interesting. A larger version which included a chorus of voices on each segment better represented the original qualities of the song, and clearly recognizable. You can hear the full version at the project website, along with an interesting visualization of the assembled recordings. The fact that the larger ensemble produced a more recognizable result, essentially averaging out the various sung renditions, is perhaps an example of the oft touted “wisdom of crowds”.

There is also a slightly more ominous set of questions from these works concerning exploitation of individuals who don’t know the overall purpose of their tasks, or about hive mentality and such, but I still find it quite interesting and am inspired to try out the Mechanical Turk for a future art project.

Sonja Navin and Mike Kimball

I recently visited two openings for artists I met at Open Studios last fall and whose work reflects my interests in highways, architectural images and the urban landscape. The artists take very different approaches, and the shows were in very different parts of the city – but having both openings on the same night was a great opportunity to see them together and simultaneously reflect upon the city itself.

First, I stopped in the relatively quiet West Portal neighborhood for a show at the Greenhouse Cafe featuring Sonja Navin. Navin draws on her architectural background to capture familiar images of the city in her paintings. Perhaps the most “familiar” image was the King Street off-ramp from I-280 in her large painting entitled 280.

Navin experienced this interchange the way many of us do, i.e., being stuck in traffic, and thus had the opportunity to visualize it in detail. She also had a painting East on N which featured a familiar view along the N-Judah metro line in the Sunset district.

Although her subject matter is often architectural in nature, her painting style features large brush strokes and irregular areas of color rather than the straight lines and precision of architectural drawings. She also had several figurative paintings, and some such as In The Haight combine both character and street elements.

Navin’s exhibition, which also features artist Kacie Erin Smith, will be on display at The Greenhouse Cafe, 329 West Portal Avenue in San Francisco through April 30.


After brief ride over Twin Peaks, I found myself descending into the Mission district for an opening at City Art Gallery, where I was particularly interested to see new works by Mike Kimball.

Like Navin, Kimball’s interpretation of the urban landscape distills it down to basic elements, but his prints and paintings feature very clean lines and simple geometric shapes. One example is his Maritime Plaza, which I immediately recognized (it is a favorite out lunch spot of mine).

Like the building it represents, the image is framed by the triangules and X-shapes of the seismic bracing. This was one of the first buildings to use this technique, which is now a familiar site on buildings in the Bay Area.

In Division Street, Kimball represents another familiar sight from daily life, the interchange of I-80 and US 101 that sits above Division Street in SOMA. The image is composed of very simple curves and lines and solid colors, from which one can distinguish the elevated structures of the highway and the shadows they cast, as well as details such as the markings (and probably graffiti) on the sides of the trailers.

Trucks and trailers also feature prominently in Kimball’s work. His “Truckograph” series features a similar graphic quality to Division Street. His larger work Meditations on a port looks at the stacks of trailers at the port as an abstract collection of boxes. Kimball bridges the industrial and abstract in this work – close up, one can see the writing and metal texture, but from a distance one simply sees the colored squares.

Kimball’s current exhibition will be on display at City Art Gallery, 828 Valencia Street, through March 28.

On Kawara, MAR. 16, 1993

Today, we consider a work from the Today series by conceptual artist On Kawara. Since 1966, he has created many paintings in this long series, each consisting of the date the painting was created in simple white lettering set against a black background.

By coincidence, the San Francisco Museum of Modern Art (SFMOMA) has in their collection MAR. 16, 1993 from On Kawara’s series:

I have seen it several times in the past, but when I wandered though the museum’s 75th anniversary exhibition a couple of weekends ago, there it was again. And there is no way I would pass up mentioning it today.

Truong Tran: the lost & found

Another review of art from the month that has past. In mid-February, I attended an artist talk with Truong Tran, part of a month-long exhibition of his work at Mina Dresden Gallery. The exhibition was presented by our friends at Kearny Street Workshop.

The gallery itself is a narrow and starkly white space. Upon entry, one is drawn first to the illuminated shapes and color fields that dot the walls. Moving closer to a particular artwork, one begins to see the meticulous detail and the variety of elements from which it is composed.

[Truong Tran.  Installation view.  Photo courtesy of the artist. (Click to enlarge.)]

As suggested by the title of exhibition the lost & found, the pieces are created primarily from found objects and materials. Tran is a self-described collector, indeed he admit, “I was a collector long before I was an artist.” This brought to mind the artist in residence program at the SF dump that I reviewed back in January. Far from a simple presentation of found objects, he constructs large-scale works from these constituent parts, placing them into boxes and the combining these boxes into larger structures. This process of found objects, containment and construction is perhaps most apparent in tower, the largest piece in the show:

[Truong Tran, tower.  Photo courtesy of the artist.  (Click to enlarge.)]

Tran cites Joseph Cornell and Donald Judd as influences, and one can see the combination of “things contained in boxes” and large minimal geometric elements reappearing in many of the works. There is also a certain polished quality to many of pieces, particularly the illuminated works that most caught my attention. For example, the piece broken and whole, shown below looks to be a very minimalist installation with lights, rectangles and solid colors. On closer inspection, one can see that each box contains bones, presumably part of a “collection.”

The use of found materials within a larger minimal pattern of boxes and solid colors appears in many of the works. The contained materials at times are provocative, such as the syringes that are placed in each box of a ladder to.

Tran is as established writer and author of several collections of poetry and a children’s book. With this exhibition, he is moving into a new medium of visual art and sculpture. However, his poetry is also very visual, as in his book within the margin where a single line of lower-case text is presented on each page. His other books published at Apogee Press have a similar visual quality to them. You can see some excerpts from a couple of the books here. Similarly, text enters into many of the visual pieces in the exhibition, such as the large letter “A” in tower. In both his written and visual works, there is a strong sense of things being “constructed”, and indeed he emphasized the concept of construction during his talk at the gallery.

One work that did not get mentioned during the talk but which drew my attention the invisible city. Once again, found materials (in this case, multicolored golf tees and thread) were arranged into a repeated rectangular pattern, but this time set against an image of a city skyline. While many of the pieces have an architectural quality to them (i.e., as “constructions”), this was only one where the image contained within was itself architectural.

[Truong Tran, invisible city. Photo courtesy of the artist. (click to enlarge)]

However, there is another level of containment, as each of the buildings contains a pornographic image – I believe they are all images of men. This is another recurring theme in many of the pieces, perhaps best exemplified via boy with butterflies which at a distance appears to be a flock of hundreds of colored butterflies frozen in mid motion. Upon closer inspection, one sees that the butterflies are cut from pornographic magazines, and it is the sections of the male bodies in these images that give the butterflies their colors and patterns.

You can see some more photos of other works from the exhibition at The Lost and Found, a visual blog created by Tran. You can also see photos from the well-attended opening at KSW’s blog.

William Leavitt, Boyce/Greenlief duo and Karl Evangelista trio

I continue to work through the backlog of art and music reviews by presenting some of the openings and performances I saw on the particularly busy and fun evening of February 19 here in San Francisco. Although the evening included both musical performances and exhibitions of visual art, music was present as a central theme throughout.

First up, we visited Jancar Jones Gallery for the opening of William Leavitt: A Show of Cards. The exhibition featured “over 300 ink drawings on index cards” (though I only counted 248) arranged in three groups on the walls of the gallery.


[William Leavitt, A Show of Cards: Installation View. Photo courtesy of Jancar Jones Gallery. (Click to enlarge.)]

The gallery’s stark white walls presented a great surface for drawings, which were sometimes very sparse and sometimes quite detailed. Many featured musical elements, such as instruments or notes on a staff. There were also mathematical pieces (such as an x-y plot of a sine function), electronic circuit diagrams, architectural drawings, animals and abstract textures.


[Click photos to enlarge.]

It was fun to scan the rows of cards, picking out individual ones for closer inspection and comparison, particular the abstracts and the references to some of my own areas of expertise (e.g., music and electronics). It turns out Leavitt has a long-standing interest in electronic music, and was featured in this article at GetLoFi alongside circuit-bending godfather Reed Ghazala.

In addition to being works of art in their own right, the cards serve as a source material for chance procedures that Leavitt uses in other works. In particular, a random subset of cards were used to generate a narrative that was incorporated into the text for his play “Pyramid Lens Delta” (the title came from the first three cards in the set). The script for the play was part of the exhibition. The back of the script contained the card set, and glancing through the text one could see where portions of the dialogue seemed to be drawn from the cards, particularly dialogue associated with Ivan, one of the characters in the play.

Leavitt has used chance processes for past works, including a theater piece The Radio which premiered in 2002. This piece includes not only dialogue but also an original score that included musique concrete. I would have liked to have seen this.


After Jancar Jones, we made a brief detour into that ambiguously defined area at the base of Potrero Hill to Project One for The Art of Noise, a visual exhibition coincident with the Noise Pop Festival. It featured large artistically altered portraits of well known musicians, as well as some installations, such Ted Riederer’s piece featuring drums covered in rose petals.


We finally ended up in the Mission District, and after a brief stop for tacos arrived at Bluesix for a pair of musical performances.

The saxophone duo of David Boyce and Phillip Greenlief. As noted in previous reviews, Greenlief’s virtuosic saxophone performances cover a wide variety of instrumental techniques. The duo weaved effortlessly between idiomatic jazz riffs and more free-form sections featuring multiphonics, noise production and vocals. The change between sections was both sudden and subtle; I was immersed in a jazz riff with long up-and-down lines or rhythmic patterns and only later would realize that we had moved to a more non-tonal (i.e., “noisy”) and arhythmic section. They demonstrate that these modes of music making need not be at odds (as they are sometimes portrayed on musician discussion lists) and can be part of a single piece of music. The performance did, however, inspire a short discussion with a friend about what is “experimental music” and why the performances this evening did or did not qualify as “experimental”.

Boyce and Greenlief were followed by the Karl Evangelista Spaceman Explorer Trio, featuring Karl Evangelista on guitar, Cory Wright on baritone sax, and Jordan Glenn on drums. Evangelista in his various groups blends jazz traditions with elements of late-20th-century experimental music. This of course led back to the question of whether or not this performance was “experimental”, particularly given strong jazz foundations on the pieces that we heard. The trio opened with loud driving rhythms and Evangelista and Wright trading long fast melodic runs. The piece “Hurdles” on Evangelista’s MySpace is quite representative. Another piece a somewhat slower groove with strong quarter notes (one might say a little bit “funkier”, more 1970s). Within this context, the melodies, riffs and one-off notes were often atonal, which helps to keep things moving forward. Overall, it was a fast-paced and virtuosic performance.

Anthony Discenza: Everything Will Probably Turn Out OK

With the month-long string of performances mostly behind me, I am trying to work my way through my backlog of reviews. Today we at CatSynth present a recent exhibition by artist Anthony Discenza at Catherine Clark Gallery entitled Everything Will probably Work Out OK. That phrase has become a bit of a mantra since the exhibit, and I keep the original card on my desk, reminding myself as I work on my music or other projects that “everything will probably work out ok.” It might not, but it probably will.  Additionally, the card, with simple black lettering on a white background, appeals to my interest in text-based art – indeed, the relationship between text and image was a central theme of the exhibition.

I particularly liked his series of “street signs”, which featured cryptic and humorous messages in the familiar rectangular shape and sans-serif type of signs used in American cities.

In addition to the gallery presentation, several of the signs were posted on streets (prior to the exhibition). In the example presented here, A LAPSE INTO THE ROMANTIC, one can see how the signs really fit the part in terms of scale, design, layout and type.

[Anthony Discenza, Lapse into the Romantic, 2007.  Photo courtesy of Catherine Clark Gallery.  Click to enlarge.]

With just a peripheral glance one could easily assume this is just another sign explaining some parking or traffic rule. A selection of the street signs were also featured in the exhibition catalogue.

Another prominent series featured plays on the “Hollywood elevator pitch”, where someone attempts to summarize their idea as “A meets B”. In Sometimes a Great Notion (Part 1). Discenza presents a wall of absurd pairings drawing from pop culture, literature, history and other sources.  Examples include “It’s M.C. Escher meets Z. Z. Top”, “It’s Le Corbusier meets Chuck Norris”, “It’s Star Trek: The Next Generation meets The Indigo Girls”, and “It’s Twitter meets SARS”. You can see a full version of the text from the piece here. He also has some extended chains as light boxes:

In addition to the visual pieces, there was also an audio installation Untitled (The Effect). In a dark room with low lighting, a disembodied female voice narrates a text describing visuals or instructions that seem disjoint but also seem to flow naturally. The text is based on fragments gathered by searching for a specific phrase on Google.

Although this quote from the press release seems to most describe the audio work, it could easily apply to the visual text-based pieces as well:

I’m very interested in text—in part because I’ve always drawn so much inspiration from literature—and specifically for the way that text can act as a kind of score, enticing the mind to construct things that don’t exist anywhere else. I’m curious about that peculiar fluidity of something experienced primarily in the imagination, and I’m fascinated by the way a small fragment of something—maybe only a few sentences, or even just a phrase—can, under the right conditions, conjure an entire narrative.

Discenza is also known for his past work which features meticulously edited and constructed video work. The exhibition does include one piece Charlton Heston: The Future Has Already Been Written in which he intersperses several Charlton Heston films on a frame-by-frame basis. It takes a moment to get used to seeing the rapidly changing images, but once one’s eyes and brain adjust, scenes and transitions become clearer (and I quickly recognized Planet of the Apes).

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 月神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.

For those in the Bay Area who may be interested in checking it out, the full information is below:

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.
