I see Mayhem are playing in the button factory next month. In general I'm pretty ignorant about metal but i like mayhem, and ordo ab chao is a very good album so i think i'll probably venture along to this. It will be my first metal gig. my friend assures me it will be the metal equivalent of an indie night in whelans but how should i behave at a metal gig? do i need to be really agressive to everybody for fear of being ripped to shreds?
