This sounds pretty astonishing that Dez Fafara didn't want to try this earlier.
This dude has played and led 2 awesome bands but never mixed them up.
But it was in the air and early this year, he announced on Twitter:
"So, yes, for the first time ever DEVILDRIVER is playing a bunch of COAL CHAMBER songs, and when you hear this shit with double kick and two guitars, there's no going back, trust that !! I waited years and tried to keep them separate, but it's time for me to embrace all that I am as a singer."
