What is the best concert you have ever been to, and why??

Rolling Stones in a small armory or Pink Floyd right after Dark Side of the Moon came out. Same armory. Pink Floyd started the show with the pulse and played the whole album in order almost exactly as they did it in the studio. Allman Brothers were just trying to get some video . Played all slow stuff I wanted to hear whipping post, one way out etc. Led Zeppelin added Louisville at least second at the end of their tour they were work out or drunk Jimmy Page couldn't keep time, plant didn't seem to mind he had his own meter. I heard some great things about other cities. People come into Kentucky thinking we're all hillbillies with no outside contact.
Sorry I get dysentery of the oral cavity even when I am typing.
