The main performance by SDC wasn't anything short of amazing. I was so impressed the first night I went, that I just had to relive the experience (and I also did hear about the special guest appearances the next day, members of The Used, and Jeremy Piven), and both were just as amazing. They played unexpected instruments and had a very good, raw, vibe to them. Aside from the drums that they played (with amazing technique and timing) they also tinkered around with construction equipment, and even had some of the fans hold some pots so they could bang on them! It was truly a different experience, some of the bandmates came out with spandex-looking jumpsuits and face make-up, but it just added to the whole "effect".
The opening bands were not as nearly as good as SDC, with half-naked wannabe "rockstar" bassest, and one of the lead singers in a tight--and I mean unnecessarily TIGHT--white spandex jumpsuit, it was just something to bare while waiting for the main band.
It was great to see the surprise after surprise these guys brought, so talented and such a awesomely different concert experience that must be seen!!
