Rainbow (also known as Ritchie Blackmore's Rainbow or Blackmore's Rainbow) were an English rock band, controlled by former Deep Purple guitarist Ritchie Blackmore from 1975 to 1984 and 1994 to 1997. It was originally established with former Elf members, though over the years Rainbow went through many lineup changes with no two studio albums featuring the same line-up. In addition to lead singers Ronnie James Dio, Graham Bonnet, Joe Lynn Turner and Doogie White, the project consisted of numerous backing musicians. The band started out combining mystical lyric themes with neo-classical metal, but went in a more streamlined commercial style following Dio's departure from the group.
Rainbow was ranked #90 on VH1's 100 Greatest Artists of Hard Rock.
In 1974, Ritchie Blackmore became infuriated at the funk/soul (or as Blackmore called it, "shoeshine music") elements being introduced to Deep Purple by David Coverdale and Glenn Hughes, as well as with the rejection from his bandmates of his suggestion to record a cover for inclusion on Stormbringer.
