While generally considered a footnote in American pop history, doo-wop music has actually had a long and hearty history, as evidenced by this abundant, three-disc set from Time/Life. Sequenced in roughly chronological order, the compilation offers some classic songs by well-known vocal groups (Dion & the Belmonts, the Four Seasons), as well as rarities from more obscure but no less gifted artists (Vito & The Salutations, Nino & The Ebb Tides).
