Atomic Rooster, formed in '69, was the missing link between the Crazy World of Arthur Brown and the pomposity of Emerson, Lake and Palmer.
Formed by Arthur Brown's Vincent Crane and Carl Palmer, it provided some of the best proto-metal/early British prog there has ever been.
Their self-titled debut album, written by Crane, was wonderfully versatile, blending pastoral folk, driving rock, slow blues and jazz, always with the steaming sound of the B3
This would be the only album featuring the trio of Crane, Palmer and Nick Graham.
John Du Caan of Andomeda would join on guitar, creating a harder rock sound.
