I thought it was great overall. The sound was great, and I liked the long noisy jams. The light show was really good (best I've ever seen was Kasabian opening for the Music -- it was even better than when Kasabian headlined a couple months later). There was a 15-minute stretch that dragged juuust a bit, but they ended strong, and the encore was good too.
There were a couple times when I was distracted by the extent to which they were using background tapes. When the keyboard player (is that Brandon Curtis?) was playing bass, they played like a classic trio, where what you saw was what you heard. But when he was on the keyboard, they had up to 4 or 5 parts coming from tapes. Once or twice, the most interesting guitar parts were not being played onstage, and that can be a little disappointing.
But overall, it was a great time. It sounded good, it looked good, and the show length was just right. Still would've liked an opener though...
