re: What's the most underwhelming concert you have been to?

Gosh there have been many concerts I've wished I never wasted the time to attend, but the single worst concert might have been the Grateful Dead in Jackson, MS with Donna Godchaux singing off key all night long. The other members were not in synch either, and it was almost painful. Thank God I also have memories of days and nights when the Dead were simply incredible.

Led Zeppelin was also disappointing when they played the Oakland Coliseum in 1977 after there was an incident backstage between the Zep entourage and Bill Graham's personnel. The tour was cancelled after the second show when Robert Plant's son died. The next tour date was supposed to be in the Superdome.
