Sum 41

Sum 41 is a Canadian rock band formed in Ajax, Ontario in 1996, led by Deryck Whibley; they moved from pop-punk hits to heavier, metal-influenced material on albums like Chuck.

Formed in 1996 in Ajax, Ontario. Frontman Deryck (Deryck Whibley) is the band's principal singer and songwriter. Early success came with All Killer No Filler (singles include "Fat Lip" and "In Too Deep"); Does This Look Infected? and Chuck mark a heavier turn in their sound. The band experienced lineup changes (guitarist Dave Baksh left and later returned; longtime drummer Steve Jocz departed; Frank Zummo appears in later lineups). Derick Whibley's rehab and lineup changes are mentioned in reviews as causes of delays around the 13 Voices period.

DeBaser's reviews trace Sum 41 from pop-punk beginnings to heavier, metal-tinged experiments. Opinions vary by album: Chuck and Does This Look Infected? are widely praised, other releases get mixed-to-negative reactions. Lineup changes and personal issues (noted rehab) affected later work.
