If you had access to a time machine, what concerts would you go back to see?

Creedance Clearwater at Woodstock, August '69! I had to be at work that weekend so no could go! 

The Allman Brothers Live at the Boston Tea Party. The first and best concert I ever saw. Duane was still alive.

The worse? Bob Dylan. He was in is country phase back then. We left after four or five numbers. It was pitiful.

Top concerts = The Dead (when they were hot), Little Feat, Radiohead, Tina Turner, Pat Benatar, The Stones (when they were hot), Death Cab for Cutie (what a name?), Richard Thompson Electric Band, Richard Thompson Solo, Carmina Burana, Beethoven's 9th

Woodstock 69’

 not to be confused with the violent crappy music at the so called Woodstock in 93? 94 ? I forget.

 Ac/dc with Ron Scott (Bon)

 Every rock/prog/heavy metal/thrash metal concert held from 1978 - 1995. Minus that Woodstock garbage show. 
Also, I would be friends with Brian Johnson, and get him blasted on Bushmills, so he missed the audition, and make sure Marc storace showed up!


  Get every autograph I could, and stop at every comic and baseball card shop, and load up.
and find the Honus Wagner card for cheap, and buy it.

The two shows that I regret missing that I actually could've seen were:  1) Genesis on their last US tour with Peter Gabriel in 1974 (a friend of mine got sick)  2) Renaissance in 75 or 76 (this time, I got sick). To make matters worse, Spirit was the opening act.....ARRGHH!!!

@roxy54 , I know what you're talking about when there's that rare spiritual connection at a concert. For me, that was the Blue Nile in 1990. They played every song from from their first two albums and it was magical from start to finish. Then they ran out of material. The audience refused to let them leave; so, they played a few more songs a second time. Cameras were there filming it, but it was never released. I ran into Paul Buchanan at the 2005 SXSW music festival and he said he never heard why that show or any other show from that tour didn't get released on video. To top it off, the opening act was Wendy MaHarry who was also excellent. She only released two proper albums + a live album with demos from her never released third album. So, I consider my self lucky that I got to see her. I would have no qualms at all going back in time to see that show again!   

Crucial Taunt 1992 at Gasworks.
