Sum 41 is a pop punk rock band from Ontario, Canada, formed in 1996 by vocalist/guitarist Derryck Whibley and drummer Steve Jocz. They were soon joined by lead guitarist Dave Baksh and after a set of bass guitarist they finally settled on Jason "Cone" McCaslin in 1999. Their first album (All Killer, No Filler) was released in 2001 and spawned their most successful single, "Fat Lip".Their follow-up album Does This Look Infected? was released in 2002. It featured a darker sound and also more serious lyrical themes. This continued onto their third album Chuck, released in 2004. In 2006, Baksh left the band to focus on his own band Brown Brigade. He was replaced by Tom Thacker, who was initially only a live member, while their 2007 album Underclass Hero was recorded as a trio. Thacker became an official member in 2009 and helped to co-write title track for their fifth studio album Screaming Bloody Murder, released in 2011. However, that album (along with Underclass Hero) had all guitar parts performed by Whibley.The bandís music is primarily pop punk and punk rock, though they have diversified over the years. They moved from pop punk (with some rap rock) on All Killer, No Filler, to melodic hardcore on Does This Look Infected? and Chuck (with the latter having alternative metal influences and lighter alternative rock), back to pop punk with Underclass Hero, and back to melodic hardcore with Screaming Bloody Murder.Sum 41 currently consists of Whibley on vocals and rhythm guitar, Tom Thacker on lead guitar and backing vocals and Cone on bass and backing vocals. Drummer Steve Jocz left the band in April of 2013, leaving Derryck as the sole remaining founding member. Jocz replacement has not been announced yet.
Alter Ego Acting: As Pain for Pleasure (see below). Also in music video for Still Waiting, they performed as The Sums and were renamed. Derryck was Sven, Dave was Holmes, Steve was Sergio and Cone was Thurston.
Call Back: Bridge to the song Subject to Change (found on japanese version of Chuck) is the same as at the end of No Reason (another, earlier song from the same album). And of course, chorus of the former song was later re-used as chorus to Underclass Hero.
Cerebus Syndrome: Half Hour of Power and All Killer, No Filler were both very upbeat, MTV-friendly pop-punk albums. They were followed by the hardcore/horror punk inspiredDoes This Look Infected? and, after that, the very sombre Chuck and equally so Screaming Bloody Murder, making the much lighter Underclass Hero a Breather Episode.
Exactly What It Says on the Tin: Half Hour of Power, although it's actually slightly shorter, with the 30 minutes length being only done with added silence after the last song.
Executive Meddling: Parodied in Still Waiting music video. At the start, their record label executive (portrayed by Will Sasso) renames the band and its individual members, stating that "number bands are out" and ""the" is in". It also parodies the executives' (supposed) lack of knowledge about music and musicians with Sasso saying, that although he has "not heard the new album, it's probably all sorts of songs about skateboarding and getting dumped" and stating band names like Green Day 75 or The Led Zeppelins.
Heavy Metal: They had an Alter Ego Acting band named Pain for Pleasure, where they performed in wigs and costumes and used nicknames - Steve (who was lead vocalist here) was Pain, Derryck (drummer) was Gunner, Dave was Pleasure and Cone was Sniper. They recorded three songs under this monicker: Pain for Pleasure, Reign in Pain and WWVII Parts 1 & 2. They also appeared as this in two of their music videos: Fat Lip (where they performed their self-titled song) and We're All to Blame (where they were announced as next band to perform on Solid Gold). Incidentally, Derryck is shown as guitarist in both of those appearances, although he actually played drums in this band.
I'm a Humanitarian: In one of their web videos, Basketball Butcher, after losing against Cone in basketball match, Steve kills him and then cooks him. Later, Derryck and Dave come in. They ask him what is for the dinner. Steve replies with "You!".
Lighter and Softer: While darker than All Killer No Filler, Underclass Hero was this to the album previous album Chuck and sounds closer to Does This Look Infected.
Mood Whiplash: Chuck is especially made of this. Not only does it put relatively softer songs ("Some Say", "Pieces" and "Slipping Away") between fast and aggresive songs, but even some of the heavier songs on the album have slower, melodic parts such as on "We're All to Blame" (aggresive verses, calm choruses) or "88" (which has calmer first verse and the outro, but is otherwise fast and heavy).
Rock Trio: During Underclass Hero era they officially consisted only of Derryck, Cone and Steve (Tom was a live member only and as such did not play on the album, nor did he appear in music videos). Screaming Bloody Murder was also recorded in three piece despite Tom Thacker already being a member of the band at that point (he did get a co-writing credit for title track, though).
