Sum 41 never fit in. Instead, they came out of the gate swinging with a signature style punctuated by pop punk singalongs and hard-hitting heavy metal proficiency. As a result, they’ve cast an unmatched shadow over popular culture, tracing back to their turn-of-the-century domination of TRL up to a rapturous set at the inaugural When We Were Young Festival. Within the span of a year, Iggy Pop tapped them for a collaboration, and they paid a fiery tribute to Metallica for MTV Icon. Their music has surged through major franchises, ranging from Spider-Man to American Pie and Bring It On.
