Sum 41 was one of the most listened to bands by me and my friends back in the day. We use to pretend we were rock stars in my garage and have an “AIR GUITAR” jam session. Those were the days, we you had nothing to worry about but being home before dinner time! Sum 41 is a Canadian rock band from Ajax, Ontario. In 1999, the band signed an international record deal with Island Records. The band released their debut album, 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.
