Rainbow, despite being thought of as a fully fledged band, had always been more of a Ritchie Blackmore solo project. The band started out as a side project when Ritchie wanted to record a cover of “Black Sheep of the Family”, which was an idea apparently rejected by Deep Purple while recording Stormbringer. Ritchie asked Elf vocalist Ronnie James Dio to sing on the song. It worked so well that the two decided to record an entire album with the rest of Elf. For the tour, Ritchie found drummer Cozy Powell and bassist Jimmy Bain. Many consider this to be the ultimate Rainbow line-up. The first three studio albums were consistent and representative of a band effort, but even through those years it was Ritchie plus any number of revolving musicians. Size M
