Problem: A musical ensemble, also known as a music group or musical group, is a group of people who perform instrumental or vocal music, with the ensemble typically known by a distinct name. Some music ensembles consist solely of instruments, such as the jazz quartet or the orchestra. Some music ensembles consist solely of singers, such as choirs and doo wop groups. In both popular music and classical music, there are ensembles in which both instrumentalists and singers perform, such as the rock band or the Baroque chamber group for basso continuo (harpsichord and cello) and one or more singers.

The four-piece band is the most common configuration in rock and pop music.  Another common formation was a vocalist, electric guitarist, bass guitarist, and a drummer (e.g. The Who, The Monkees, Led Zeppelin, Queen, Ramones, Sex Pistols, Red Hot Chili Peppers, R.E.M., Blur, The Smiths, Echo and the Bunnymen, The Stone Roses, Creed, Black Sabbath, Van Halen, Rage Against the Machine, Gym Class Heroes, The Stooges, Joy Division, and U2.) Instrumentally, these bands can be considered as trios. This format is popular with new bands, as there are only two instruments that need tuning, the melody and chords formula prevalent with their material is easy to learn, four members are commonplace to work with, the roles are clearly defined and generally are: instrumental melody line, rhythm section which plays the chords or countermelody, and vocals on top.  In some early rock bands, keyboardists were used, performing on piano (e.g. The Seeds and The Doors) with a guitarist, singer, drummer and keyboardist. Some bands will have a guitarist, bassist, drummer, and keyboard player (for example, Talking Heads, Gerry and the Pacemakers, Small Faces, King Crimson, The Guess Who, Pink Floyd, Queen, Coldplay, The Killers and Blind Faith).  Some bands will have the bassist on lead vocals, such as Thin Lizzy, The Chameleons, Skillet, Pink Floyd, Motorhead, NOFX, +44, Slayer, The All-American Rejects or even the lead guitarist, such as Death, Dire Straits, Megadeth and Creedence Clearwater Revival. Some bands, such as The Beatles, have a lead guitarist, a rhythm guitarist and a bassist that all sing lead and backing vocals, that also play keyboards regularly, as well as a drummer.

Problem: 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.
