Best small show was Death by Stereo with Brat Attack, Bigwig, Big D and the Kids Table, and a young The Flatliners. No real security, and the stage was just a raised platform.
Medium show is a tie between Strung Out and Coheed and Cambria. The venues for both were awesome. Coheed played the Commodore (which was great), while Strung Out played this theatre-turned venue called The Rickshaw. Just amazing performances from them both.
Stadium show, Iron Maiden. Hands down. They put on such an awesome show.
