Singer Dion DiMucci, better known simply as Dion, epitomized the indigenous music of the Bronx streets where he grew up. In 1957, he teamed with three neighborhood pals—Fred Milano, Angelo D'Aleo and Carlo Mastrangelo—to form a vocal group that earned a reputation as the best street-corner singers for miles. Dion and the Belmonts (named for Belmont Avenue, in the Bronx) perfected four-part harmonies while falling under the spell of rock and roll. The quartet combined the doo-wop sound of their home turf with a raft of rock and roll and R&B influences that included Fats Domino, Bo Diddley, Jerry Lee Lewis and Elvis Presley. Dion and the Belmonts scored their biggest hit, "Where or When," in 1960, but the group found itself being steered in a polished, adult-pop direction and Dion left to reclaim his rock and roll roots. In 1961, he hit upon a loose, swaggering style that he could call his own with the songs "Runaround Sue" and "The Wanderer."
