Remember the guy in the wheelchair in Slingblade? That guy is Vic Chesnutt, singer, songwriter, recovering alcoholic, among many things. From the movie Slingblade you would never know  how talented he is musically and poetically. I found one of his performances online at SouthernShelter.com from the 40 Watt in Athens, Georgia. They have a bunch of other artists' live performances online as well. You might check them out.

One of Vic's most notable songs is "Supernatural."  Here's that song performed Live at the 40 Watt.

Contrast Vic's Version with Live's, two very different versions, both beautiful. Live gives him a great deal of credit, deservedly so, for his work on creating the song!

Lives Recording of Supernatural (I believe on MTV Unplugged)
 

And Yes the Wheelchair is Alcohol related for Vic, he's been in it since he was 18 years old.
