Oficially licensed exact repro of this 1975 single, originally issued on Metronome. The sweet, hypnotic melodies and the monotonous beats by Michale Rother (Neu!), Hans-Joachim Roedelius (Cluster) and Dieter Moebius (Cluster) and the repetitive lyrics, "Immer Wieder...rauf Und Runter..." make up this Krautrock/electronica classic.
