Dio's musical career began in 1957, when several Cortland, New York musicians formed the band, The Vegas Kings. The group's lineup consisted of Dio on bass guitar, Billy DeWolfe on lead vocals, Nick Pantas on guitar, Tom Rogers on drums, and Jack Musci on saxophone. The band changed its name to Ronnie and the Rumblers. In 1958, the band again changed their name to Ronnie and the Redcaps. Musci left the band in 1960, and a new guitarist, Dick Botoff, joined the lineup. The Redcaps released two singles: The first single was "Conquest"/"Lover" with the A-side being an instrumental reminiscent of The Ventures and the B-side featuring DeWolfe on lead vocals. The second single was "An Angel Is Missing"/"What'd I Say" featuring Dio on lead vocals for both tracks.
