One singer you won’t likely hear on a ’50s oldies station is Harry Belafonte, yet he was one of the most popular singers of that decade. He made a name for himself in the emerging folk music genre, with five gold albums between 1955 and 1963. For a time, he was outselling Elvis Presley. His repertoire anticipated world music; he incorporated musical traditions from the Caribbean, Africa, Ireland and the U.S. in his singing. By the early 1960s, his brand of smooth traditional folk was overtaken in popularity by grittier singer-songwriter acoustic music, rock-and-roll and soul.
