Behemoth would make sense, I'd love for them to be on it. I went to a backstage afterparty at Mayhem 09, which had some bands with fairly goofy members (KSE, Black Dahlia, All That Remains), so there was a lot of clowning around, they were playing a bunch of Michael Jackson and dancing with girls, and then I looked and saw three hulking guys leaning against the wall with some facepaint still smeared on the collars of their shirts. No smiles. That is how Behemoth attends dance parties.
Thanks to all who said hi at Mayhem this summer
