Recorded at the Dierks Studio in Stommeln, the album featured a line up of Edgar Froese, Chris Franke and Steve Schroyder with guests Udo Dennebourg (flute) and Roland Pualyck (synthesiser). Released in Germany on the OHR label, the influence of the album was immense, with the band creating imaginative sound-scapes previously unheard on record. This Esoteric Reactive edition is newly re-mastered and includes three bonus tracks: 'Ozillator Planet Concert' has never been released on CD and was issued as part of the 1971 double album "Ossiach Live". Also included are both sides of the classic 'Ultima Thule' single issued in Germany in 1971. The release fully restores the original album artwork and includes a lavishly illustrated booklet
