In the early 1960s, he was discovered by Byron Lee, the band master of the Dragonaires, who brought him to Jamaica. His styles included ska, R&B, soul, gospel and calypso. He is credited with inventing spouge music, a fusion of ska, calypso, and R&B music. Opel performed duos with Doreen Shaffer and Hortense Ellis, and in 1964 was backed by Wailers Bob Marley and Peter Tosh on "Mill Man", "Hairy Mango" and "A Time to Cry".
