Black Coal,

Nearly everyone in the world can rattle off the great African-American musical forms. Jazz, blues, R&B, soul, hip-hop, house, gospel. One influential genre is always left off of the list: a folk music known as rock n’ roll. Rock n’ roll was a term originally coined to market the white-friendly version of a genre that already existed; prior to 1965, the line between rock n’ roll and R&B was thin: Ike Turner recorded and released “Rocket ‘88’ ” in 1951 and, while its Chess Records release reached number one on the Billboard R&B chart, it is regarded by many as the first rock n’ roll record.
