Ray Charles was the musician most responsible for developing soul music. Singers like Sam Cooke and Jackie Wilson also did a great deal to pioneer the form, but Charles did even more to devise a new form of black pop by merging `50s R&B with gospel-powered vocals, adding plenty of flavor from contemporary jazz, blues, and (in the `60s) country. Then there was his singing; his style was among the most emotional and easily identifiable of any 20th century performer, up there with the likes of Elvis and Billie Holiday. He was also a superb keyboard player, arranger, and bandleader.
