Seeing this on Saturday, can't wait. Mainly going for Testament but I'm sure Lamb of God will be cool too. I've never listened to much KSE so I'm pretty indifferent towards them. Will probably hit up the merch booth during their set.
May 4th - Volbeat, Anthrax
June 14th - Crowbar, Battlecross
June 24th - Goatwhore (?)
