I actually got a ticket to see him in Ridgefield, CT next month. I haven't seen him live for some reason since roughly 1994 or 95 when he played Tuxedo Junction in Danbury. Why do I remember that gig so well? It severely damaged my hearing for years. No joke.
His technique and knowledge of the fretboard is truly frighting. I read an interview with him once where he was talking about hearing a song on the radio he liked and had the whole song solo and all transposed in his mind=scary.
