Known as the King of the Blues, guitarist B.B. King has been performing and recording since the 1940s. He grew up sharecropping in Mississippi and learned to play gospel music on the guitar when he was a teenager. In the late 1940s he turned to playing blues and moved to Memphis, Tennessee to start a music career. After popular performances in clubs and on radio, he kicked off his recording career with "Three O'Clock Blues" (1951), a top hit on the R&B charts. King's early records in the '50s produced some R&B hits, but mainstream success eluded him. He and his band toured almost non-stop, performing hundreds of shows a year and building an audience. He finally had breakthrough success in the late 1960s, when white audiences began to discover rock's debt to the blues. ..[Full version]
