Oh, ok. Well, we're very different people.
There are shows I go to sober, of course. Usually the more expensive it is, and the more I'd want to remember it when I'm old (Nick Cave, Roger Waters, Deep Purple, shit like that) the more likely I am to go sober.
But I don't think I've ever been to a metal show sober. Half the fun for me is the mindless, drunk thrashing about.
