Evolution/Revolution: The Early Years (1966–1974) is a two-CD compilation of live stand-up comedy recordings by comedian and actor Richard Pryor, that predate his 1974 mainstream breakthrough album That Nigger's Crazy. The album was primarily compiled from tapes recorded by Laff Records between 1966 and 1974. By 1968, Pryor had only recorded and released one album up to that point, the eponymous debut that was released by Dove/Reprise and featured a much milder Pryor.
