This album dates from 1972 and is an unprecedented display of drone-rock on the heavier, psychedelic side of the '70s German underground. Guru Guru's lineup changed periodically, and throughout the '70s, the project took contributions from Conny Plank and Hans-Joachim Roedelius, among others, and were tightly connected with the Kraftwerk off-shoot Harmonium. This album is undoubtedly one of their greater works, alongside UFO and Hinten recorded by the essential trio of Ax Genrich on guitar, Uli Trepte on bass, and leader Mani Neumeier on drums and keyboards.
