Behemoth have confirmed that they will be playing the 2012 Bloodstock Open Air Festival.The band were originally due to play the festival in 2010, but were forced to cancel their appearance after frontman Nergal was diagnosed with Leukemia.In an official press release, the vocalist states:"We couldn't do the show for obvious reasons last time, I was in a deep shithole with my sickness, but I really felt obliged to come back and do Bloodstock as soon as possible.""We are really fortunate that they invited us back, we couldn't turn it down, and this is the perfect opportunity to make this up to the people that missed us last time. For us it's a great pleasure to come back to the UK after two years, and I can promise we will bring full production - lights, pyro - it's gonna be awesome and we can't wait.""This is not only the first time we headline a festival, but also our first open air appearance in the UK, so it's gonna be special!"Bloodstock Open Air 2012 will take place at Catton Hall August 9-12.
