Sum 41 is a Juno Award-Winning Canadian pop punk band from Ajax, Ontario. The current members are Deryck Whibley (lead vocals, guitar, keyboard/piano), Cone McCaslin (bass/vocals), and Steve Jocz (drums/vocals).

The band was formed on the 41st day of summer (hence the name Sum 41).

Underclass Hero is Sum 41's first concept album, fifth overall studio album and first release without former guitarist Dave Baksh.

Underclass Hero marks a step in a bold new direction for the group, whose three full length album's, 2001's All Killer, No Filler, 2002's, Does this Look Infected and 2004 Chuck have sold over 7 million units worldwide. 'You Can't help buy grow a little', says Whibley about the band's musical and lyrical maturity. 'We now see the artistic side of music. We wanted to make this the most artistic punk-rock record we could. We approach music differently now. Things now have a purpose. We care about the craft of it now.' The is Sum 41, better than ever...and this time no regrets.
