Greatest live disappointment

The 1999 International Progressive Music Festival in San Francisco had some wonderful surprises as well as some real disappointments. In general, the festival was wrought with sound system disasters. Both days performances were about 2 hours late. Bondage Fruit opened the fest and blew everyone away despite the sound issues. The bands that disappointed me the most were Lana Lane and The Rocket Scientists whose only real prog moment was a horrifying ItCotCK cover. Porcupine Tree just sounded like AOR to me. They were tight, but...meh.  Gong did their thing and were mildly entertaining, but not really my thing.

Overall I enjoyed the festival. The remaining acts (Par Lindh, Brand X, Buckethead, Magma) were all incredible. But the unenjoyable ones were just that. I guess thats the trouble with festivals, you get some not so good with your good.

Not Strictly Prog, But Thin Lizzy when I saw them supporting Deep Purple a little while back. I was only 15 at the time,(teenage progger here :) ) and it kind of shattered one of my early loves for a band. Them not playing "whiskey in the jar" was a crime beyond comprehension to me, and there was just none of the energy that any Thin Lizzy album is full of. I understand the problem is the sad lack of Phill Lynnot (R.I.P.) but it was still a sad day.

It's probably been done before somewhere, but this thread was prompted by watching the telly this morning, when my wife wouldn't let me get her off the computer

I put on Sky Arts to watch Pink Floyd perform DSOTM (from the Pulse DVD, but without any of the other tracks).

I remember seeing this tour, and reliving it this morning, reminded me of just how awful I thought it was. Yep, although DSOTM is a five star classic in my mind, I felt at the time, and again today, just how awful the gig was. The terrible female vocals on Great Gig In The Sky, the vastly unnecessarily overextended Money (with poor old Dick having the indignity of a bunch of gyrating females behind him whilst trying to remember how to play the sax), the obligatory percussionist doing the obligatory jumping up and down whilst, at the same time, saving Nick Mason from being a silent witness, and the conclusion I reached at the time that this was merely a band going through the motions without the man who was passionate about the lyrics he had written.

Controversial, I know. But, what was your biggest live disappointment? A gig or tour you had really looked forward to, but ended up being a total dud.
