Survival kit for Metal Concert?

I'm a metal head myself I would say lots of black and chains band aids are good for cuts and scrapes some booze and maybe some weed if your down with that kind of thing also I wouldent bring any weapons make sure to wear big boots your best bet if its your first concert don't get too close to the mosh pit in fear of getting hurt it can get pretty gruesome that's awesome your going to see a 7 x that's my favorit band I'm jelous lol
