Profile of the performer Circles:
Excellent ambient/experimental "Krautrock" duo of the early 1980's in similar realms to Cluster and Harmonia. They made 3 now rare and collectable albums on the independent [l=Einhorn Music] label.
Related projects include: D.O.C. aka Das Organisierte Chaos (more rock/new-wave) and Kofler & Leitert.
