By the way, Attila is only playing 6/15 to 7/11, so only the first half of the tour.
Not really familiar with most of these bands but I'll check them out. I've heard good things about Man Overboard, Mac Lethal, and MC Lars. The Chariot puts one hell of a live show so I might check them out if they aren't clashing with anyone else.
They'll probably save the main stage bands for the later announcement, they're just naming off the bands that are going to be on the smaller stages probably.
12/15 Red Fang (?)
12/27 The Black Dahlia Murder
1/14 Shai Hulud (?)
