I do know that Slayer was planning a small tour this summer. Not sure on any details other than that. I would be willing to bet that All That Remains is on the tour with Zombie, maybe Hollywood Undead.
Of course it could an Unholy Alliance tour with Slayer, Zombie, ATR and AILD. That wouldn't be bad at all.
I really thought Zombie would be a perfect headliner for Uproar.
