I've been watching him now and then on YouTube for a few years. I hadn't seen this one - thanks for posting.
He's incredible - can play anything that has strings put on it, no matter how many. Have you seen his shovel guitar? I think he also plays something with only 2 strings on it, don't remember what that's called.
He also has a nice instructional finger picking video. Seems to be a good teacher and a really nice guy.
