Rosco Gordon in the 1950's was on Sun. He invented 'Rosco's Rhythm' that so influenced the Jamaican musicians who would create Ska and Bluebeat. In 1982 he was 're-discovered' after decades out of the business. His comeback gig was at London's 100 Club and the tapes were running. The original LP went to a single pressing of 1000 and is ultra rare.
