In June 2023, during their performance at Hellfest, Sum 41 was approaching the end of a significant chapter in their career, as they had announced that they would be going on hiatus after completing their last tour. Prior to this, their latest album was "13 Voices," released in 2016, marking a notable return for the band as it featured a more mature sound and reflected lead singer Deryck Whibley's struggles and recovery from past challenges. The Hellfest set included fan-favorites such as "Hell Song" and "We Are All to Blame," showcasing their energetic blend of punk rock and alternative sounds that had solidified their place in the music scene since the early 2000s. This performance is particularly poignant as it represents a farewell to their dedicated fan base, encapsulating their career full of ups and downs while highlighting their evolution as a band.
