Of the bands I saw: Pain and Satyricon were awesome. Devin was kinda fun, but a bit of a pantomime with the interactions between him and the recorded Ziltoid segments, which weren't as funny as the old broadcasts he did when the album came out. Obituary were cool, but any more than an hour or so and they get a bit dull live. Insomnium were pretty boring. Tarot were very good, but don't put on much of a show. Unarguable songs though.
Highlight of the day was the Dio Memorial Gala gig down the road later that evening. See separate thread
