KenKen GS installation at Gridspace

KenKen GS is a new installation work that continues Galbraith’s exploration of a tightly-coupled yet non-linear and generative relationship between image and sound.
The work’s compositional basis includes the structure and expanded numerical content of four KenKen puzzles, historical color scales that propose different mappings from musical pitch to color hue, and 15 resonant acoustic frequencies taken from various locations within Gridspace.
KenKen GS is generated in real-time by custom software, and features abstract graphics formatted with reference to the wooden grid of 12 two-foot-square “cubicles” normally used for exhibitions at the Gridspace storefront gallery. The piece has a linear temporal structure and loops after the 19-minute video animation sequence completes.

Composition 2010 ETC (video excerpt)
April 9, 2011
Composition 2010 ETC is a single-channel video (duration 4:08) created from footage shot at the Experimental Television Center (ETC) studio during my 2010 residency. Using analog video modules that can convert audio waveforms into video signals I recorded 30 minutes of attempts to draw a straight horizontal line across the video screen using my custom analog synthesizer modules. This “straight line” action has been a motivation behind other works of mine and references the score of American composer La Monte Young’s Composition 1960 No. 10 which reads “draw a straight line and follow it”. My Composition 2010 ETC edits this tightly integrated sound/image footage down to a four-minute mix. By including ETC in the title of the work I wanted to pay homage to the Experimental Television Center studio which closed in June, 2011 after a forty-year history as an important center for experimental video work.
Double Square video excerpt
October 17, 2009
Excerpt from Double Square (2009) color animation with sound, 5 min. 54 sec.
Double Square was created in part by extending a 1968 Philip Glass work for two flutes into an audiovisual score used by custom software to simultaneously generate a grid-based animation and microsonic, multichannel sound.

lgOpre
an audiovisual installation
lgOpre (luh-GOP-ruh) is an audiovisual installation of multichannel sound and projected digital animation created with real-time software that links vintage grid pattern algorithms with vinyl record lock-groove samples. The software behind lgOpre, written by the artist, uses customized abstract image generation routines (c.1970), appropriated color schemes, and self-similar number patterns to create an animation that is also a visual controller for a modular digital sound studio. Each of the 34 grid pattern building blocks used for lgOpre is mapped to its own set of processed and unmodified lock-groove samples. The color of the underlying grid is used to select which sound will play as the basic grids from each animation frame are visually highlighted in turn for a determinate duration before advancing to the next frame. Aleatoric color scheme variants introduce a degree of chance to the sound-image mapping.
Compositionally, lgOpre first introduces each visual building block as a full-screen matrix using black and white, grayscale or a few saturated colors to create monochromes or relatively simple patterns accompanied by solo sound samples. The screen splits in half horizontally, then vertically, producing four quadrants with increasing pattern complexity. New color schemes and faster sequencing within a single animation frame trigger the look of blocky color video games or visualized computer core dumps and densely layered multichannel sound.
Locked grooves and the title of Galbraith’s 2002 video Open Research which juxtaposed animated black and white ‘big bit’ grids with human-sized inflatable sculpture from the late-1960s helped give lgOpre its name: locked groove Open research.
