An awesome punk/rock band. Sum 41 is very talented and when performing live, they sound almost the exact same as they are on the album. (A lot of times, even better.). Deryck Whibley can write extremely powerful lyrics and his talent really shines in Screaming Bloody Murder, the 5th studio album that they released. Their fans are called "skumf*ks" and only the best fans can call themselves that. The band is currently made up of 4 members:

Deryck Whibley- lead singer, lead guitarist (Bizzy D)
Steve Jocz- drummer, vocals (Stevo 32)
Jason McCaslin- bassist, vocals (Cone)
Tom Thacker- guitarist, vocals (BrownTom)

*Tom Thacker replaced Dave Baksh- the original member of the band before his departure in 2006 to focus on his band Brown Brigade.

The band started out as a NOFX cover band called Kaspir with just Steve and Deryck. After that, they changed the name to Sum 41. Sum 41 was formed in 1996, 41 days into summer. (Hence the name.)

Before Dave left the band, Sum 41 had an alter ego band- Pain for Pleasure. They would dress like a 1980's heavy metal hair band by wearing leather jackets and crazy wigs. Stevo is the lead singer while Deryck plays the drums.

Sum 41 has released 5 studio albums so far.
