The notion of concrete sound, and the specificity of the listener's relationship to sound sources in space are central to [The User]'s approach. Beyond being sound-producing instruments, the Coincidence Engines installations are free-standing, quasi-architectural constructions that are integral to the viewer-listener's absorption in fields of sonorous expression. The work's hybrid, interdisciplinary approach is simultaneously engaging and sophisticated. Coincidence Engines' potent experiential qualities provide multiple points for audiences' interactions with an innovative form of contemporary cultural expression.
