Before he was doubling over audience members with profanity-laced sketches and stories... igniting a comic revolution, Richard Pryor was a young joke man struggling with his identity. In the late 1960s and early 1970s Pryor transformed himself from a nonthreatening, middlebrow comic to a controversial, X-rated sensation, and in turn forever transformed the landscape of comedy in the process. For the first time, those contrasting worlds have been brought together on Evolution/Revolution: Early Years (1966-1974), a 2-CD set chronicling the groundbreaking metamorphosis that predated Pryor's 1974 breakthrough album, That Nigger's Crazy.
