Dieter Moebius is one of the most important protagonists of avant-garde electronic music in Germany. Alongside his bands Cluster and Harmonia he participated in numerous collaborations (e. g. with Brian Eno, Mani Neumeier / Guru Guru and Conny Plank). 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. "Adventures in sound, a world brought to life by the most remarkable characters and atmospheres." (Asmus Tietchens)
