YesNo (2010) for solo theatrical performer, live motion tracking system, interactive sonic environment, and computer controlled spotlight. I continue to be interested in the many ways that gestures (physical, facial, sonic, social) inform our awareness of the world around us. Without relying on verbal language, a shrug, a sigh, a grimace or nod can speak volumes. We all know this. YesNo takes this as its starting point - a set of gestures that link sight and sound in their own private little conspiracy. My main job as a composer/performer is tampering with the evidence. The work makes use of a live video-based motion tracking system that drives an interactive sonic environment and a computer controlled spotlight. The work was premiered as a part of "A Theater of Sound: Intermedia Performance Works by David Bithell" at the Dallas Museum of Art on February 19, 2010.
