Deryck Jason Whibley (born March 21, 1980), nicknamed Bizzy D, is a Canadian musician, singer, songwriter, and record producer, best known for his work as the lead vocalist, rhythm guitarist, keyboardist, main songwriter, and producer of the rock band Sum 41.
He lived with his mother, who moved from one place to another during his childhood. Finally they stayed in Ajax, Ontario, Canada, where he spent his adolescence with his mother and stepfather.
Whibley formed Sum 41 with drummer Steve Jocz, bassist Richard Roy and vocalist Jon Marshall. They were originally called Kaspir, and were a NOFX cover band. In 1999, the band signed an international record deal with Island Records. The band released their debut album, "Half Hour of Power" in 2000, then All Killer No Filler in 2001. The band achieved mainstream success with their first single from the album, "Fat Lip", which reached number-one on the Billboard Modern Rock Tracks chart and remains the band's most successful single to date. All Killer No Filler was certified platinum in the United States, Canada and in the UK. The band has since released six more studio albums: Does This Look Infected? (2002), Chuck (2004), Underclass Hero (2007), Screaming Bloody Murder (2011), 13 Voices (2016), and Order in Decline (2019). The three albums before Screaming Bloody Murder have been certified platinum in Canada.
