Rainbow are a British/American rock band formed in London and Los Angeles 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 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.
