Graveland don't play live, though they should (is Capricornus even officially a part of the band, any more?). I generally don't go to concerts, but if it were Graveland... Listen to some awesome music, have a few pints, and hang out with Polish skinheads. Sounds like an ideal night out, to me.
I was going to say Burzum, but that's even less likely than Darkthrone playing live again.
