The band released the album Screaming Bloody Murder, on Island Records in 2011 to a generally positive reception, though it fell short of its predecessors' commercial success.

Following a final worldwide headlining tour, the band are set to disband after their induction into the Canadian Music Hall of Fame in March 2025.

[1] Sum 41 has its origins in the band Kaspir, which was formed by Deryck Whibley and Grant McVittie in 1994, inspired by Weezer and Nirvana.

As time went on, the band's founding drummer was replaced by Steve Jocz and the music became increasingly inspired by NOFX, particularly their 1991 album Ribbed.

[10][11] The Introduction to Destruction and later the Cross The T's and Gouge Your I's DVDs both contain the self-recorded footage, which show the band performing a dance to "Makes No Difference" in front of a theatre.

[45] The video also appeared on the group's live DVD, Sake Bombs and Happy Endings (2003), as a bonus feature.

[49] A UN peacekeeper, Charles "Chuck" Pelletier, called for armoured carriers to take the hotel's occupants out of the hot zone.

[73] On May 10, 2006, Dave Baksh, via a statement through management, announced that he was leaving Sum 41 to work with his new band, Brown Brigade, which has a more "classic metal" sound.

[89] Sum 41 released a greatest hits album in Japan titled 8 Years of Blood, Sake and Tears in November 2008.

[93] Drummer Steve Jocz confirmed that Tom Thacker was now an official member of Sum 41, and would take part in the writing and recording.

[95] In an interview with Tom Thacker, some working titles for songs for the new album were confirmed, including "Panic Attack", "Jessica Kill" and "Like Everyone Else".

[99] In an interview with Canoe.ca, Steve Jocz said that while producer Gil Norton was originally hired to engineer the new album, he was only around for a week and Sum 41 self-produced the record.

[109] A music video was also produced for the first single, "Screaming Bloody Murder", but it was left unreleased due to its content and difficulties with executives of the band.

[112] It was announced on the band's official website that they would be postponing indefinitely all upcoming tour dates for 2011 while Whibley underwent treatment.

[112] In 2011, Sum 41 was nominated for a Grammy Award for Best Hard Rock/Metal Performance for the song "Blood in My Eyes", but lost to the Foo Fighters.

[113][114][115] In February 2012, the band shot a music video for the song "Blood in My Eyes", the third single from the album, with director Michael Maxxis in Los Angeles.

[127] On June 9, 2014, Whibley said on his Facebook page that he was working on new Sum 41 music out of his home studio to get ready to record some new tunes.

[159][160] The same day, the band also announced their seventh studio album, Order in Decline, with a set release date of July 19, 2019.

[166][167] On July 18, 2019, the band performed a medley of Metallica songs including "For Whom The Bell Tolls", "Enter Sandman", and "Master Of Puppets" at Sirius XM studios.

[182][183][184][185] On October 8, 2022, during their Does This Look All Killer No Filler Tour, Sum 41 performed at the Unipol Arena in Bologna, Italy, drawing over 14,000 attendees, the band's largest concert ever held in Europe.

The song is a return to the pop-punk sound of the band's early career, meaning it will be part of the Heaven side on the upcoming album.

[200][201] The song is in the style of the band's more recent heavier metal sound, meaning it will be part of the Hell side on the upcoming album.

[209] Before the release of Half Hour of Power, and up until the departures of Dave Baksh and Steve Jocz, Sum 41 occasionally played as an alter ego 1980s heavy metal band called Pain for Pleasure during shows.

During the Don't Call It a Sum-Back Tour in 2017, Pain for Pleasure appeared performing the song at the end of their show with guitarist Tom Thacker replacing Jocz as the vocalist.

[210] Sum 41 has collaborated with many other artists, both live and in the studio, including: MC Shan, Tenacious D,[212] Ludacris,[213] Iggy Pop,[214] Pennywise,[215] Bowling for Soup,[215] Unwritten Law,[216] Mike Shinoda,[217] Treble Charger,[218] Gob,[216] Tommy Lee,[219][220] Rob Halford,[220] Kerry King,[4] Metallica,[221] Ja Rule,[222] DMC,[223] and Nothing,Nowhere.

[228] Jocz recorded his first video as director for a Canadian band, The Midway State,[229] and McCaslin started a side project with Todd Morse of H2O and Juliette and the Licks.

[262] Underclass Hero was as a revival of the band's pop-punk style,[270] however differentiated itself from their early work through its heavy use of acoustic guitars, complex vocal harmonies, pianos and organs.

[262] 13 Voices and Order in Decline saw the band continue in this heavier direction, incorporating elements of hardcore punk, metalcore and thrash metal.

[280] Sum 41's influences include Weezer, Slayer, the Police, Devo, Megadeth, Pennywise, Refused, Rancid, No Use for a Name, the Vandals, Anthrax, Carcass, Dio, Judas Priest, Foo Fighters, Green Day, NOFX, Lagwagon, Face to Face, Nirvana, the Beatles (including John Lennon's solo work), Elvis Costello, Beastie Boys, Run–D.M.C., Rob Base and DJ E-Z Rock, Metallica, Guns N' Roses, and Iron Maiden.
