Rex Garvin was a pioneering American R&B singer, songwriter, and bandleader whose energetic style helped shape the sound of mid-century soul and rock ‘n’ roll. Active from the 1950s through the 1970s, he was best known for co-writing “Over the Mountain, Across the Sea” and leading his group Rex Garvin and the Mighty Cravers. His powerful vocals, driving rhythms, and gospel-infused arrangements captured the spirit of early rhythm and blues, leaving a lasting influence on later generations of soul and funk musicians.
