Hence is the third collaborative release from Oren Ambarchi and Jim O'Rourke. Building on the refined combination of electronics and acoustic instrumentation found on their previous releases, Hence presents two side-long pieces combining synthesizers, heavily effected guitar tones, and tabla rhythms played by special guest Uzhaan. On the first side, an explosive opening chord sends out ripples of sparse, irregularly pulsing guitar and synthesizer tones, aleatorically changing in pitch and jumping around the stereo image. The second side begins in a similar area, combining tabla, shimmering Leslie cabinet guitar tones, and a wandering melodic line. Undergoing a series of subtle variations, this initial area eventually builds to a climax of twittering synthesized birdsong reminiscent of Alvin Curran's '70s work. Combining influences from post-minimalism, the pioneers of live electronics, and eastern music into a unique sound world, Hence is a seductive work from two of the most singular sensibilities in contemporary music.
