Wikipedia : This day (September 1, 2005), in Oxford, Mississippi, died R. L. Burnside, an American blues singer, songwriter and guitarist.
R. L. Burnside : Inspired by John Lee Hooker’s ’50s hit Boogie Chillun’, R.L. began singing blues and playing guitar. In addition to the Hooker 45 rpm there were other local forces thatinfluenced R.L as well, such as Mississippi Fred McDowell and Ranie Burnette.
@allmusic : North Mississippi guitarist Burnside was one of the paragons of state-of-the-art Delta juke joint blues
@last.fm : ike other country blues musicians, he did not always adhere to 12- or 16-bar blues patterns, often adding extra beats according to his preference. He called this “Burnside style” and often commented that his backing musicians needed to be familiar with his style in order to be able to play along with him.
