Descendents and The Mighty Mighty Bosstones will headline the Lock Up Stage at this year's Reading and Leeds festival, it's been announced.
King Blues, The Bronx and Flogging Molly will also perform.
Other acts due to appear on the stage across the August Bank Holiday weekend include Capdown, Street Dogs, Sharks, Bedouin Soundclash and Hot Water Music.
Mike Davies, curator of the stage, said: "2011 is the year that Punk Rock broke out... again. There are so many great groups around and I truly believe that we have managed to get 24 of the best bands possible to play on the Lock Up Stage.”
Reading and Leeds takes place from August 26-28 and will be headlined by My Chemical Romance, Muse and The Strokes.
