I'd like to hear some Michel Angelo before I comment, I've heard great things about his playing and that he has a two neck guitar with necks placed at 120 degrees so he can play both at once. This sounds like a damn good idea for a self-acompanying guitarist 'cause ever time you play a string with one hand you rule out playing another note simultaneously with the other on that same string. I've only heard one track but that was years ago and I don't remember much about it.
