In August 2019, Sum 41 performed "Fat Lip" during the Vans Warped Tour 25th Anniversary Show, marking a significant moment in their career as they continued to celebrate their legacy. Prior to this live recording, the band had released their album "13 Voices" in 2016, which showcased their evolution, blending punk rock with more mature themes. By 2019, Sum 41 was actively touring and had solidified their reputation as a pivotal band in the pop-punk genre, partly due to the enduring popularity of songs like "Fat Lip." The Vans Warped Tour, a notable platform for punk and alternative music, was an appropriate venue for the performance, emphasizing the band's connection to the community that helped launch their career in the early 2000s. This live recording highlights both their nostalgic appeal and ongoing relevance in the music scene.
