Now a nostalgia-trip brand name owned by co-founder Otis Williams, they were one of the great vocal groups at Motown Records. The Eddie Kendricks falsetto (his "Keep On Truckin'" is in the 70s time capsule). The studly leads of David Ruffin and successor Dennis Edwards. The choreographed steps. The embarrassing late-60s fop finery. The peak: a 1968 post-riots TV special with The Supremes. They got occasional 80s marketplace juice via collaborations with Hall & Oates and Rick James.
