This German hard rock machine, with British belter John Lawton, (later of Uriah Heep) gave birth to one of the best heavy rock albums of the early 70's. From the screaming vocals of "Ride In The Sky" (with its brass opening reminiscent of Zeppelin's "The Immigrant Song" and an almost "thrash metal" riff) to the progressive/hard R&B of "Toxic Shadows", to the lumbering, Sabbathish doom of "Keep Goin", this album never lets up for a second. Fans of Black Sabbath, Uriah Heep, Deep Purple and Led Zeppelin must have this in their collection! Lawton is one of the best singers in hard rock, and the musicianship of the group is tremendous. Very heavy indeed for a 1970 release.
