Sum 41 and Don Broco are the headliners for this year's Slam Dunk Festival, it has been announced. Taking place in September in the hopes that all limits on social contact will have indeed been lifted by then, the festival (celebrating its fifteenth anniversary) will also play host to While She Sleeps, We Are The In Crowd, Four Year Strong and more. 

Leeds will get the party on 4 September and Slam Dunk will move onto Hatfield the next day. It looks like Alkaline Trio and The Used will no longer be heading to the fest at all, but several other names booked for 2020 have reconfirmed their attendance, including Escape The Fate and Wargasm. 

"It was a shame we have had to move the festival again from May however we feel the guidance now is clear enough to know the event will happen in September" festival director Ben Ray said.

Slam Dunk Festival takes place 4 September in Leeds and 5 September in Hatfield.
