Sadly I say this lineup is officially cheap.
Slipknot
Slayer
A yet unnamed band...who most likely will be lamb, of god since they're pimping their new album
Either....Devil Wears Prada, As I Lay Dying, Asking Alexandria
Only second stage
For some reason...anthrax
Either the above 3
Whitechapel
High on fire
And....battle of bands winner
Wow never thought it could kill itself this bad
