Nickelback is a Canadian rock band formed in 1995 in Hanna, Alberta, Canada. The band is composed of guitarist and lead vocalist Chad Kroeger, guitarist, keyboardist and backing vocalist Ryan Peake, bassist Mike Kroeger, and drummer Daniel Adair. The band went through a few drummer changes between 1995 and 2005, achieving its current lineup when Adair replaced drummer Ryan Vikedal. Nickelback is one of the most commercially successful Canadian groups, having sold more than 50 million albums worldwide and ranking as the eleventh best-selling music act, and the second best-selling foreign act in the U.S. of the 2000s, behind The Beatles.

Around 2001, Chad Kroeger started "studying every piece, everything sonically, everything lyrically, everything musically, chord structure. I would dissect every single song that I would hear on the radio or every song that had ever done well on a chart and I would say, 'Why did this do well?'" Kroeger said that Nickelback's single "How You Remind Me" sold so well because it was about romantic relationships, a universal subject, and contained memorable hooks.  To record their third album Silver Side Up, Nickelback collaborated with producer Rick Parashar. The album was written before the release The State and was recorded at the same studio. The album was released on Tuesday, September 11, 2001. The album peaked number 2 on the Billboard 200 with over 177,000 copies sold in its first week and peaked number 1 at the Canadian albums chart making the band's first album to do so. The single "How You Remind Me" was a number one single on the Mainstream and Modern rock charts, as well as the pop chart. It also peaked at number two on Adult Top 40 and became the Billboard Hot 100 number one single of the year for 2002. The next single was "Too Bad", which also reached number one on the Mainstream Rock Chart. The final single from the album was "Never Again", which also one hit on Mainstream Rock.  In 2002, Chad Kroeger collaborated with Josey Scott on the Spider-Man theme song, "Hero". This recording also featured Tyler Connolly, Mike Kroeger, Matt Cameron, and Jeremy Taggart. In 2002, Nickelback released their first DVD Live at Home.  In 2003, Nickelback released The Long Road. The album was certified 3x Platinum by the RIAA in March 2005 and it had sold 3,591,000 copies as of April 2011. It has sold over 5 million copies worldwide and in 2003 only the album sold 2 million copies worldwide. It debuted at No. 6 on the Billboard 200. This was their first album produced by Joey Moi, a former classmate of the band's.  It was ranked No. 157 on Billboard's 200 Albums of the Decade. It spawned five singles. The lead single was "Someday" . The band also released "Feelin' Way Too Damn Good" as a single, which peaked at number 3 on the Mainstream Rock Charts. "Figured You Out" was also released as a single and topped the Mainstream Rock Charts for 13 consecutive weeks.
