Bloodstock Open Air has added Ancient Egypt-obsessed death metallers, Nile, and historically-extremely-important-although-not-really-as-good-as-they-used-to-be black metallers, Mayhem, to its 2012 line-up. And…errr…that’s about it. Both bands are making their Bloodstock debuts, and both bands are going to be UK festival exclusives for Bloodstock this year, but then again we doubt there were many other festivals fighting to be first ones to knock either band’s booking agent’s doors.
