Colin Andrew Sheffield (samples, processing) & James Eck Rippie (turntables, processing) are an improvising duo who sculpt with pre-recorded sound to create works of abstract beauty.
Their debut long-player, 2001's critically acclaimed Variations, was recorded "live" with no additional production. Each of the album's pieces utilizes sounds from a single acoustic instrument as its sole source material.
Since the release of their album, Sheffield & Rippie have continued to perform and to record, expanding the concepts utilized in the Variations cycle.
