In the current trend of posts - how about gigs you went to full of expectation that left you feeling really deflated at the end?
Always going to be subjective, of course, but I think for me it was Joe Bonamassa some years back at the Royal Albert Hall. At that point I had most of his back catalogue and a live DVD at Rockpalast and was excited at the prospect of seeing someone who was widely being lauded as the 'new' talent in blues guitar perform live.
It was dire. How they managed to get such a poor sound at the RAH is beyond me, but they did - only sorting it out around half way through. And it was all about Joe showing off his licks all night. All speed, no taste, no space, almost a different guitar for each track for Mr Bonamassa to masturbate with. Eric Clapton shuffled on to a 1 minute standing ovation, dusted off one of his bog standard, middle of the road solos and got another 2 minute ovation at the end. Paul Jones shuffled on and played what might well have been a blindingly good harmonica solo but Joe masturbated over it and you couldn't really tell. Did I say it was dire?
