An 11-track compilation album, arranged in chronological order; the tracks on Side A all date from 1968, which is when producer Norman Whitfield chose Motown vocal group The Temptations to be the purveyors of his new musical vision, a driving psychedelic funk/soul fusion underpinned by messages of black power and social revolution. The radical and exhilarating music collected on Psychedelic Soul make it the only truly essential Motown album. An edited-down, superior version of the way overlong Psychedelic Soul (Motown B0000582-02, 2003).
