The 10th anniversary of the Bloodstock Open Air will take place at Catton Hall in Derbyshire, UK from August 13th – 15th.

Organizers report: "We have just received news that BEHEMOTH frontman Nergal was rushed to hospital, and as a result has been forced to cancel scheduled Behemoth shows, including Bloodstock. Our thoughts and best wishes go out to Nergal and his family, and we wish him a speedy recovery.

Taking their place will be English doom legends CATHEDRAL, who make their Bloodstock debut with this last minute confirmation.

Sadly OCTOBER FILE have also had to cancel their performance due to vocalist Ben Hollyer exacerbating his current stomach injury at their recent Sonisphere festival set.

Explains Ben: “Unfortunately I have had to pull out of performing at BOA this year and our first year too! I am absolutely gutted that we can't be there. A recent injury involving my abdominal muscles tearing down the middle has made performing not possible. Have a good BOA!!”

Stepping up at the 11th hour to replace them are rising folk flavoured black metallers WINTERFYLLETH.

Vocalist/guitarist Chris Naughton states:

"Winterfylleth are truly humbled to be asked to play at one of the finest metal festivals going on within our fair shores. It is a privilege for us as existing fans of the festival to now be considered amongst some of the great bands that are playing at the festival this year. We are looking forward to standing alongside acts like Gorgoroth, Behemoth and many others, bringing our brand of English inspired Black Metal to such a discerning and committed festival following. We look forward to seeing you there. Hail Bloodstock."
