“Epiphenomenal Boogie: Light-Sound Singularities In Patterned Time by Joe Grimm (25:00, live triple-projector performance, 2008) Using three 16mm projectors, black-and-white loops are projected through primary-colored gels to produce various mixed color phenomena at the screen. Noisy audio is produced by a circuit matrix that uses screen-mounted light sensors to modulate the feedback within projectors’ built-in audio circuits. Sound is played back through a massive, resonant gong. A psychedelic, stroboscopic exploration of the physical qualities of light, electricity, shaking metal, and vibrating air.”
