Good news & bad news. I was at the Hatebreed show last night talking to a few of the band members and Mayhem Fest became the topic of discussion for a few minutes. From what I was told Chelsea Grin are not playing but unfortunately Emmure is definitely playing. Hatebreed and Shadows Fall are not playing but they all but verified every band I have listed so far:
Five Finger Death Punch
In This Moment
Job For A Cowboy
Children Of Bodom
I'm still working on trying to nail down the main stage opening band and a few more of the smaller stage bands.
1-13 Philip H. Anselmo & The Illegals
