Canadian pop-punk troupe Sum 41 will break up after 27 years together. Announced on Monday, the band revealed it will cease operations following a worldwide farewell tour and the release of its ninth album, Heaven :x: Hell.

“‘Being in Sum 41 since 1996 brought us some of the best moments of our lives,” the band wrote on social media. “We are forever grateful to our fans both old and new, who have supported us in every way. It is hard to articulate the love and respect we have for all of you and we wanted you to hear this from us first.

“Sum 41 will be disbanding,” it continued. “We will still be finishing all of our current tour dates this year, and we’re looking forward to releasing our final album Heaven :x: Hell, along with a final worldwide headlining tour to celebrate. Details will be announced as soon as we have them.

“For now, we look forward to seeing all of you skumfuks on the road and are excited for what the future will bring for each of us.”

Guitarist Deryck Whibley, drummer Steve Jocz, bassist Richard Roy, and vocalist Jon Marshall formed Sum 41 in Ontario in 1996, originally as a NOFX cover band. Whibley eventually assumed the role of lead singer and the band rocketed to stardom in 2001 with its full-length debut All Killer No Filler and the single “Fat Lip” ascending the charts. The album also contained other hits “In Too Deep” and “Motivation” and ultimately went platinum in the U.S. and U.K. and three-times platinum in the band’s native Canada.

The success of All Killer No Filler set the band up for fame for years to come, dominating 2000s pop-punk alongside acts like Blink-182. A string of well-charting albums followed with Does This Look Infected?, Chuck, and Underclass Hero through the rest of the 2000s. Whibley became a tabloid celebrity in light of his four-year marriage to Avril Lavigne, for whom he produced a pair of singles in 2006 among other acts. A series of lineup changes over the years left Whibley the last remaining original member. The group’s most recent studio effort, Order in Decline, arrived in 2019.
