They’ll join headliners Iron Maiden, Metallica and The Prodigy for the 40th anniversary of rock festivals at Knebworth Park on July 4-6.
Among others also added to the bill are the Sisters Of Mercy, Voodoo Six, Limp Bizkit, Carnifex, Dropkick Murphys, Silverstein and rockney icons Chas And Dave.
Scott Ian of Anthrax says: “It’s one of those phone calls you only dream about. I’m so excited for Anthrax to be a part of the biggest and best Sonisphere ever – can’t wait to destroy Knebworth again!”
Townsend comments: “Sonisphere is an institution that’s really exciting, among bands we absolutely love. We can’t wait to take a studio break and come entertain you there.”
Chas And Dave add: “We went down well at Knebworth in 1979. Not surprised we got a return booking!”
Earlybird weekend tickets remain on sale at £170 for a limited time via www.sonisphere.co.uk. The festival deposit scheme is also in operation, meaning you can reserve your ticket for an initial payment of £50.
