R.L. Burnside - Someday Baby
(Unofficial video)

This song was released on his 2004 album, A Bothered Mind, and Burnside died a year later at the age of 78. I haven't found the rest of his music to be anything like this track. Granted though, I haven't listed to a lot of it. What stood out the most when I was reading about him is that he once killed a man over a game of dice. Brutal. He was convicted of murder and sentenced to six months in prison, but his boss was able to pull some strings and get the sentence shortened (as if six months isn't already a short enough amount of time to spend incarcerated for killing someone) because R.L. was such a good tractor driver.
