The Penguins were an American doo-wop group from the 1950s, best known for their hit single, "Earth Angel (Will You Be Mine)". The group, composed of Cleveland Duncan, Curtis Williams, Dexter Tisby, and Bruce Tate, helped shape the rhythm and blues genre with their harmonic vocal style. Their music was characterized by smooth, melodic lines and tight harmonies, which had a significant influence on the emerging rock 'n' roll scene. Despite their short-lived career, The Penguins' contribution to music history remains notable, particularly through "Earth Angel", which has become a classic of the doo-wop genre.
