Disco's most soulful vocal group began in 1960s Philadelphia as [a=The Volcanos (2)], and were also called The Moods. Gene Faith was the original lead vocalist, with Earl Young, [a=Jimmy Ellis (2)], guitarist Dennis Harris, keyboardist Ron Kersey, organist [a=John Hart (9)], bassist Stanley Wade, and drummer Michael Thomas. But by the time they'd gone through various identities and emerged as the Trammps in the mid-1970's, the lineup featured lead vocalist Ellis, Harold Wade and Stanley Wade, Robert Upchurch, and Young.
