Interesting collection of bands.  Slipknot and Underoath lol.

Sounds like fun.  Be safe, though.  A small tip:  If you see someone go down, or for some reason you need to get through the crowd quickly, you'd be surprised how fast people get out of the way if you use a small pressure point behind their ear or another one under their jaw with your thumb.  Or if you just grab their face and push on their nose so they turn.  Good crowd control techniques to know for very condensed areas.

Scrappy lives!!! Where are you bud???
