Following the previous announcement that this year's festival will be headlined by platinum record sellers The All-American Rejects, there's been some juicy bands added to the line up.
Rock Sound cover stars, We Are The In Crowd, will be flying into the country exclusively for Slam Dunk, and they're set to be one of the favourites of the weekend.
Kings of ska, Less Than Jake, will join Goldfinger and Zebrahead. They previously headlined the festival alongside Reel Big Fish back in 2011, but will be making a special appearance this year.
US pop punk favourites Motion City Soundtrack and Hit The Lights will also be joining the line up after a year's absence.
State Champs will be making their UK festival debut at Slam Dunk, while Chunk! No, Captain Chunk! and A Loss For Words will be returning. UK group Marmozets will also be playing in support of their forthcoming debut album.
There's an updated line up poster after the jump!
