The Best of Rainbow compiles 16 of the best tracks from Rainbow's first seven studio albums, wisely avoiding 1977's live On Stage release. The first two tracks from their debut album, 1975's Ritchie Blackmore's Rainbow, showcases the instant bond that was formed between Blackmore and Ronnie James Dio, especially on "Man on the Silver Mountain." Blackmore changed the band for the following year's Rainbow Rising, with Jimmy Bain replacing bass player Craig Gruber, and Cozy Powell taking percussion duties away from Gary Driscoll. Adding keyboard player Tony Carey helped tracks like "Starstruck" and the lengthy "Stargazer" to sound a little more dimensional and fluent than the group's first effort. All of 1978's Long Live Rock and Roll have Rainbow settling in to a heavier sound with faster guitar riffs, proven on the frantic "Kill the King" and on the string accompanied "Gates of Babylon."
