I was goint to start a thread on this very same topic yesterday, and we were probobly standing together in the same area. I had the very opposite reaction. I couldn't have been more disappointed with Mars Volta's performance. First off, the sound was about the worst that I've heard at any concert, really for both bands, but for Mars especially. Next, they played just shy of one hour which is about standard, but they only played 4 songs IIRC. I really dig all their albums and really like their spacey progressive stuff, but I thought they went way out of their way on that end during their performance. Also, I was quite disappointed in Aldrete's playing, not that it was bad, but I was hoping that he was going to break away a bit from the recorded album playing and venture off into a bit more of his "shredding" stuff or at least get out from what was safe and push it a little. I thought the drummer sure did that. He's a freakin stud and really stuck out as the best performance by far of the whole band. I wasn't impressed with Omar's playing either. I really don't think he's a great player, and actually he's a bit on the spazzy/sloppy side, but I thought he was even worse at the show. His play is pretty loose and I wasn't too crazy about his approach which almost seems like he trys to overplay things constantly instead of being tastefull like Aldrete. All in all, I was totally disappointed aside from the drummer's performance. I really went to the show to see those guys, but they certainly didn't live up to the hype. I was hoping for a lot more live, but I think I've come to the realization that they simply are a studio band and that it's pretty tough to replicate their sound and vibe live. I'm not sure that I'd see them again live, but I think I should give them one more try when they're doing another headline tour. Hopefully then it will be better.
