Formed by four members from rival high school bands in Toronto, Sum 41 developed their fun and funky sound while touring with bands like The Mighty Mighty Bosstones, Offspring and Blink 182. Their second album, All Killer No Filler, features punk mixed with metal, hip-hop and rock, and includes the single 'Fat Lip'. 'Fat Lip' achieved significant chart and commercial success; it topped the U.S. Billboard Modern Rock Tracks chart as well as many other charts around the world. The song remains the band's most successful song to date. After "Fat Lip", two more singles, entitled "In Too Deep" and "Motivation", were released from the album. "In Too Deep" peaked at #10 on the Modern Rock Tracks chart, while "Motivation" peaked at #24 on the same chart.
