Sum 41 to co-headline Slam Dunk 2020 with Don Broco

Slam Dunk Festival just got a whole lot bigger!

US pop punk legends Sum 41 have been announced as the co-headliners alongside previously confirmed Don Broco.

Speaking to Kerrang! magazine, frontman Deryck Whibley, who will make his debut with his bandmates at the alternative all-dayer, said: “Slam Dunk is a festival we’ve been wanting to do for a long time, and until now we’ve never been able to pull it off.

“Scheduling and all that stuff has meant we’ve not been able to play in previous years, which has been frustrating.

"To finally be appearing at Slam Dunk is a great feeling – it’s been a long time coming. It’s something we’ve always wanted to do, and it’s a festival I’ve continually heard great things about. Sum 41 playing Slam Dunk just makes sense to me.”

Billy Talent, The Used, The Story So Far, Basement, Dream State and Grayscale have also been added to the impressive bill for the festival, which returns to Leeds, Temple Newsam on May 23rd and Hatfield Park in Hertfordshire on May 24th.

NOFX will return with 'Punk In Drublic' and We Are The In Crowd will reunite exclusively at Slam Dunk, following their hiatus in February 2016.

Fat Mike of NOFX - who is curating the lineup for the takeover, which will see an appearance from punk stars Pennywise - said: "I don't actually remember playing last year.... so we decided to do it again this year! I probably still won't remember, but this time we're gonna video tape it!”

Hardcore legends Your Demise will celebrate the 10th anniversary of their acclaimed album ‘The Kids We Used To Be’, a decade after their last performance at the festival.

Previously confirmed acts include The Wonder Years, State Champs, Mayday Parade, Knuckle Puck, Four Year Strong, Bayside, Ice Nine Kills, Issues, Hands Like Houses and Motion City Soundtrack.
