Dieter Moebius and Hans-Joachim Roedelius (aka Cluster) released this, their first album, after Conrad Schnitzler (Kraftwerk, Tangerine Dream) left the group originally known as Kluster in 1971. On the outer edge of German space rock, Cluster 71 stands as a testament to minimalist "cosmische" music. The three untitled tracks are exploratory, ever-changing pieces which focus on guitar distortion and synthesizer wails. This album deserves the many accolades it"s been given, and holds up as an early landmark in the history of beatless ambience.
