Canadian alternative rockers who have managed not only to win the hearts of their homeland, but also to achieve worldwide success, are heading to Moscow on their world tour in support of a new album. The Canadian punk rockers will play their gig at Moscow`s Arena club on Wednesday July 6. The band that started in pop punk and punk rock genres over the years of their creativity ended up heading towards heavier sound in later albums. However their punk core has always remained. Many of the band`s songs raise sharp political and social problems. Perhaps this became one of the reasons to invite Russian Noise MC to warm the audience before the punk stars step on stage. Noise MC is today Russia`s buzziest and most scandalous rapper, whose texts are mostly politics-oriented and disgraceful to Russia`s authorities. Sum 41 is a band formed in 1996 in Ajax, Ontario, under the name Kaspir. However soon they went for a shorter and a more symbolic name for their band. They named it Sum 41 as it actually came to existence on the 41st day of summer. Well, that is how it was. The band`s line-up changed a few times. Today its members include the founders - ex-husband of another music star, Avril Lavigne, Deryck Whibley and drummer Steve Jocz, along with two more musicians Tom Thacker and Jason McCaslin. Sum 41 released their debut album Half Hour of Power in 2000. Their first full studio album, All Killer, No Filler became platinum in Canada, the United States and in the UK in 2001. These two recordings are mainly pop punk, punk rock and rapcore to Mainstream success came to Sum 41 with their first single Fat Lip. The band has since released four more studio albums: Does This Look Infected?, Chuck, Underclass Hero (all three becoming platinum in Canada) and the latest, Screaming Bloody Murder, released in March 2011.
