Bloodstock Open Air’s 10th Anniversary Festival will take place at Catton Hall, Derbyshire, UK from August 13th – 15th.

Organizers have issued the following update:

"BOA is thrilled to confirm the final headline slot for the 10th anniversary festival will be taken by legendary US metallers TWISTED SISTER. Capturing the spirit of rebellion, the multi-million selling New Yorkers enjoyed a hugely successful career, adored by metal fans and feared by the “moral right”, before disbanding in the mid-80’s. Reuniting in 2001 to headline the New York Steel benefit concert in the wake of the September 11th attacks, the band made their first steps towards returning to the stage after fourteen years, delighting fans across the world.

Now Bloodstock is honoured to have Dee Snider, Jay Jay French, Eddie "Fingers" Ojeda, A. J. Pero, and Mark "The Animal" Mendoza for their first UK outdoor festival performance since 1983’s Monsters Of Rock. Never failing to deliver anything short of a spectacular live set, the foundations of Catton Hall are set to shake as classics such as 'I Wanna Rock', 'Leader Of The Pack', 'Burn In Hell' and 'We’re Not Gonna Take It' have all in attendance singing their hearts out.

Finnish warriors ENSIFERUM bring the battle back to Bloodstock in 2010 making a welcome return to the main stage. These heroic Viking Metallers are no strangers to BOA, having laid waste to the stage in 2006. With four albums worth of aural artillery, these Finns are well-equipped to rally the metal warriors in attendance, ensuring victory at BOA’s Decennial celebration, at this exclusive festival appearance.

German power-metallers EDGUY also make a welcome return to the Bloodstock stage, which the band are excited about gracing again. Charismatic frontman/metallic maniac Tobias Sammet is especially looking forward to returning to the UK for Edguy's only UK Festival appearance: “We've played Bloodstock twice and I am more than happy to be part of the 10th anniversary edition of the festival once more. I love playing England because I feel they understand us so well. I mean, despite the accent. I seriously love: Magnum, Robin Hood, tea, Def Leppard, John Wayne, I love England. I love the Indian cuisine, I admire mostly British bands, I love to hear proper English, and who am I to tell you are driving on the wrong side of the streets?”

The band lineup for the festival so far: HEAVEN & HELL, CHILDREN OF BODOM, FEAR FACTORY, TWISTED SISTER, OBITUARY, ROSS THE BOSS, RAGE, ANDROMEDA, BEHEMOTH, DEVIN TOWNSEND, DORO, LEAVES EYES, SUFFOCATION, CANNIBAL CORPSE, KORPIKLAANI, GWAR, AMORPHIS, GOJIRA, SONATA ARCTICA, GORGOROTH, BLOODBATH, BLACK SPIDERS, EDGUY, ENSIFERUM.
