All the names so far one can hardly argue with but let me throw in a name of a guy who I saw in London back in the early 70's. Michael Jackson played at our Students Union in the East End, the first gig of his UK tour. He came in, sat down and played a two hour set; just him his accoustic guitar and no sound system. It was a privelege to be there.

I had never heard of him before: I've never heard of him since although I am sure he is dead by now. All I know is that concert was onehelluvanexperience.
