I saw we had a "best concert" thread:

but what was the WORST concert you've ever been to?

For me it was Metallica / Guns & Roses at the L.A. forum YEARS ago.....Metallica was all right (never been too much of a fan of theirs) but GNR, whom I have always just LOVED, were just awful that night....so much so that my then boyfriend and I decided to leave before the show was over, and beat the rush and the traffic home.

How about you? Any shows for which you wish you could have gotten back the hours of your life you spent on them?
