The Four Tops are an American vocal group formed in Detroit, Michigan, in 1953 as the Four Aims. They were one of the most commercially successful American pop music groups of the 1960s and helped propel Motown Records to international fame. The group's repertoire has incorporated elements of soul, R&B, disco, adult contemporary, doo-wop, jazz, and show tunes. Lead singer Levi Stubbs, along with backing vocalists Abdul "Duke" Fakir, Renaldo "Obie" Benson and Lawrence Payton remained together in the group for more than four decades, performing until 1997 without a change in personnel. Along with fellow Motown groups the Miracles, the Marvelettes, Martha and the Vandellas, the Temptations, and the Supremes, the Four Tops helped to establish the "Motown sound"; pop-friendly soul and R&B with a clean, polished production quality. They were notable for having Stubbs, a baritone, as their lead singer, whereas most other male and mixed vocal groups of the time were fronted by tenors.
