I saw TVotR opening for NIN.
I was sitting about center in the first part of the stadium seating.
It really was not a good performance. I like them, and I have two of their CDs. Yet, first of all, the lighting was terrible, to the point where none of my friends believed me about some of the band members race. Secondly, all we could hear was the wall of sound.
So, we couldn't see them, and we could hear them, but nothing distinct.
I would just blame it on the venue, but NIN sounded and looked great.
So, yeah, I was dissapointed. People who had never heard of TVotR at the show went as far to say that they were terrible, but even if my only thoughts on them were from the performance, I wouldn't even go that far.
