Rainbow

Rainbow (also known as Ritchie Blackmore's Rainbow or Blackmore's Rainbow) were a British hard rock band formed in Hertford in 1975 by guitarist Ritchie Blackmore. Established in the aftermath of Blackmore's first departure from Deep Purple, they originally featured four members of the American rock band Elf, including their singer Ronnie James Dio, but after their self-titled debut album, Blackmore fired these members, except Dio, recruiting drummer Cozy Powell, bassist Jimmy Bain, and keyboardist Tony Carey. This line-up recorded the band's second album Rising (1976), while Long Live Rock 'n' Roll (1978) saw Bob Daisley and David Stone replace Bain and Carey, respectively. Long Live Rock 'n' Roll was also the last album with Dio before he left the band to join Black Sabbath in 1979.

Rainbow's early work primarily used mystical lyrics in a hard rock/heavy metal style, then moved in a more pop-rock direction following Dio's departure from the group. In 1979, Blackmore and Powell revamped the group, recruiting three new members—singer Graham Bonnet, keyboardist Don Airey and another then-former Deep Purple member, bassist Roger Glover—and this line-up gave the band their commercial breakthrough with the single "Since You Been Gone" from their fourth studio album Down to Earth. With Joe Lynn Turner, who replaced Bonnet in 1980, Rainbow recorded three more albums—Difficult to Cure (1981), Straight Between the Eyes (1982), and Bent Out of Shape (1983)—that had commercial success similar to the band's previous albums. Other members of the band during this period were drummers Bobby Rondinelli and Chuck Burgi and keyboardist David Rosenthal. The band split in 1984, when Blackmore and Glover re-joined Deep Purple.
