What should I wear to a metal show in the winter time, at the Crazy Donkey?

I'm going to the crazy donkey in a few days to see behemoth, suffocation, devildriver, goat and thy will be done. I've been to the venue before, but not in the winter time. I just wanted to know what i should wear/bring to the show, if the venue doesnt have a coat check? cuz i would rather not wear a winter coat for the whole night lol. I know my question may seem stupid, but i just wanted to know what i should wear. speak soon.
