Multi-instrumental and electronics duo of Dieter Moebius and Hans-Joachim Roedelius formed 1971 in Berlin. The band had their roots in the trio Kluster with Conrad Schnitzler.
Early Cluster recordings involved guitars, keyboards and home-made electronics and are of a very experimental nature, on the edge of what is known as Krautrock. Association with Michael Rother from Neu! led to the hybrid project Harmonia and a more musical direction for Cluster. Collaborations with Brian Eno were also recorded, and further recordings covering a wide range of styles.
In 1981 Cluster as a duo were put on hold, but have reformed on many occasions. Both members have also been prolific with solo works and other projects.
