Daniel Johnston. He's a folk singing Christian fundamentalist with Bi-polar. I really like his early stuff, he played his music on old out-of-tune pianos and guitars. He would record a bunch of songs on to cassette tapes and pass them out. Then, he would do it again because he didn't have a way to dub.
I hadn't heard of him until I saw this documentary about him.
