The album sold few copies on its UK-only release in August 1970, and is remembered because two of the band members, Ralf Hütter and Florian Schneider-Esleben, later went on to form the group Kraftwerk. It was produced by Konrad "Conny" Plank. ‘The studio was in the middle of an oil refinery. When we came out of the door we could hear the sound of those big flames burning off the fumes – all kinds of industrial noises.’ — Ralf Hütter
