On the outer edge of German space rock, Cluster '71 stands as a testament to minimalist "cosmische" music. The three untitled tracks composed and performed by Moebius and Roedelius are exploratory, ever-changing pieces with focuses on guitar distortion and synthesizer wails, though each goes far beyond. This album deserves the many accolades it's been given, and holds up as an early landmark in the history of beatless ambience.
