Rainbow was formed in 1975 by guitarist Ritchie Blackmore after quitting Deep Purple, the band he had founded and led since the late 60's. Teaming up with American vocalist Ronnie James Dio, bassist Craig Gruber, keyboard player Mickey Lee Soule and drummer Gary Driscoll, the group's 1975 debut "Ritchie Blackmore's Rainbow" was taking heavy metal a step further. Their 1978 album "Long Live Rock'n'Roll" established them as a best selling group. During the following decade the band released 8 LPs before Blackmore left to rejoin Deep Purple.
