Disco's most soulful vocal group began in 1960s Philadelphia as The Volcanos (2), and were also called The Moods. Gene Faith was the original lead vocalist, with Earl Young, Jimmy Ellis (2), guitarist Dennis Harris, keyboardist Ron Kersey, organist John Hart (9), bassist Stanley Wade, and drummer Michael Thomas.
