We aren’t quite sure who wrote this; Elmore James and Sonny Boy Williamson II both recorded it in the ’60’s, but it’s probably from much earlier. Anyway, Duane Allman, who was most likely influenced by Elmore James and other slide guitar players, probably learned this and lobbied the rest of the Allman Brothers to cover it.
The Allman Brothers Band is pretty much the 800-pound gorilla of Southern rock; it’s hard to talk about the genre without talking about them. They formed in 1969 and recorded two studio albums, their eponymous debut (1969) and Idlewild South (1970), but it wasn’t until their first live album, 1971’s At The Fillmore East, that people began to take notice of them. This is from that live album.
