Cluster (Dieter Moebius & Hans-Joachim Roedelius) is a German experimental musical group that has influenced the development of contemporary popular electronic and ambient music for more than 30 years. Cluster has amassed a large discography as a group, including their landmark eponymous releases and a critically acclaimed collaboration with Brian Eno.

Apart from Cluster, Roedelius and Moebius have numerous solo projects and individual collaborations to their credit as well. Though commonly categorized as Krautrock and Kosmische Musik, in fact they are neither; rather, they rightly belong in a unique category known as Cluster.
