Wow... I just seen this video
and it has to be one of the most bitchin' things i have ever heard. I don't know much about acoustic blues and poked around a bit and found out it was called driftin' blues. there is a tab on ug but not that great.

Anyways, can anyone tell me so songs or artists similar to this? I have got to start playing this stuff.
Obviously there's Robert Johnson, Son House, Skip James and those types. For a more recent artist who is excellent, check out Keb Mo.
