Plank is still credited as a composer together with Hans-Joachim Roedelius and Dieter Moebius on all tracks.

Cluster II was recorded at Star-Studio in Hamburg, Germany in January 1972.

It was Cluster's first release for legendary krautrock label Brain,[2] a relationship which would last until 1975 and include the subsequent album Zuckerzeit as well as the first two Harmonia albums, a group which included both remaining members of Cluster and Michael Rother of Neu!.

Julian Cope included Cluster II in his "Krautrock Top 50" list.
