“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,” frontman Sum 41 Deryck Whibley told Kerrang. “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.”
NOFX’s Fat Mike added: “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!”
2019’s edition saw notable sets from the likes of Bullet For My Valentine, Glassjaw and Turnstile.
