We previously reported that Chimaira and DevilDriver would be appearing on separate episodes of MTV's Headbanger's Ball. Now we have some more light to shed on the situation. We're proud to announce that Chimaira's episode will air on Valentine's Day (Andre 3000 wishes you all a Happy Valentine's Day, by the way), 2.14. As for DevilDriver, they'll be filming their segment on 2.27, and it will most likely air the following day, 2.28.
