Honestly, I wouldn't want it any other way...my hearing will likely be shot after day 1 regardless. It might be the one time I bring those ear plug things to drown the sound a bit to a show.
But yeah, over the whole weekend I'd be looking to see: The Black Dahlia Murder, The Acacia Strain, First Blood, Reign Supreme, Protest the Hero, Bane, Shipwreck, Cruel Hand, Naysayer, The Greenery, Rotting Out, and Every Time I Die.
All the bands I don't have listed are obviously still worth checking out though, to be honest the Sunday line up is kind of lacking for me. If ETID weren't playing that day I'd definitely just go for Friday and Saturday.
