Dieter Moebius is one of the most important protagonists of avant-garde electronic music in Germany. Alongside his bands Kluster/Cluster and Harmonia, he participated in numerous collaborations (with the likes of Brian Eno and Mani Neumeier/Guru Guru).
Karl Renziehausen, visual artist and constructor of sound sculptures, was a fringe member of the Forst/Weser Uplands creative community (home to Moebius, Rother, Roedelius et al). His profound understanding of computers motivated Moebius to enter into a collaboration with him. The music: surrealist, minimal / experimental electronics.
