Some context: Slayer is an American thrash metal band from Huntington Park, California. The band was formed in 1981 by vocalist/bassist Tom Araya and guitarists Kerry King and Jeff Hanneman. Slayer's fast and aggressive musical style made them one of the founding "big four" bands of thrash metal, alongside Metallica, Megadeth and Anthrax. Slayer's current lineup comprises King, Araya, drummer Paul Bostaph and guitarist Gary Holt.
In late 1987, Slayer returned to the studio to record their fourth studio album. To contrast the speed of Reign in Blood, the band consciously decided to slow down the tempos, and incorporate more melodic singing. According to Hanneman, "We knew we couldn't top Reign in Blood, so we had to slow down. We knew whatever we did was gonna be compared to that album, and I remember we actually discussed slowing down. It was weird--we've never done that on an album, before or since."  Released in July 1988, South of Heaven received mixed responses from both fans and critics, although it was Slayer's most commercially successful release at the time, debuting at number 57 on the Billboard 200, and their second album to receive gold certification in the United States. Press response to the album was mixed, with AllMusic citing the album as "disturbing and powerful," and Kim Nelly of Rolling Stone calling it "genuinely offensive satanic drivel." King said "that album was my most lackluster performance," although Araya called it a "late bloomer" which eventually grew on people.  Slayer returned to the studio in spring 1990 with co-producer Andy Wallace to record its fifth studio album. Following the backlash created by South of Heaven, Slayer returned to the "pounding speed of Reign in Blood, while retaining their newfound melodic sense." Seasons in the Abyss, released on October 25, 1990, was the first Slayer album to be released under Rubin's new Def American label, as he had parted ways with Def Jam owner Russell Simmons over creative differences. The album debuted at number 44 on the Billboard 200, and was certified gold in 1992. The album spawned Slayer's first music video for the album's title track, which was filmed in front of the Giza pyramids in Egypt.  Slayer returned as a live act in September 1990 to co-headline the European Clash of the Titans tour with Megadeth, Suicidal Tendencies, and Testament. During the sold out European leg of this tour tickets fetched up to 1,000 Deutschmark ($680 USD) on the black market. With the popularity of American thrash at its peak, the tour was extended to the US beginning in May 1991, with Megadeth, Anthrax and opening act Alice in Chains. The band released a double live album, Decade of Aggression in 1991, to celebrate ten years since their formation. The compilation debuted at number 55 on the Billboard 200.  In May 1992, Lombardo quit the band due to conflicts with other members, as well as his desire to be off tour for the birth of his first child. Lombardo formed his own band Grip Inc, with Voodoocult guitarist Waldemar Sorychta, and Slayer recruited former Forbidden drummer Paul Bostaph to take his place. Slayer made its debut appearance with Bostaph at the 1992 Monsters of Rock festival at Castle Donington. Bostaph's first studio effort was a medley of three Exploited songs, "War," "UK '82," and "Disorder," with rapper Ice-T, for the Judgment Night movie soundtrack in 1993.

Some context: 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.
In 1996, the band recorded and released their first full-length album, Curb. "Fly" was included on both Hesher and Curb and was the first single produced by Nickelback. In 1997, Brandon Kroeger left the band and the band searched for a new drummer. Later that year Mitch Guindon joined the band, but he decided to leave in 1998 because he started working in a car company. In Summer 1998, Ryan Vikedal joined the band.  Roadrunner A&R Ron Burman told HitQuarters that one of his West Coast scouts sent him the self-released album and, suitably impressed, he travelled to Vancouver to see them perform live. Although an unknown property in the industry at the time, the venue was packed out. In Burman's words: "I immediately got the chills! I thought their song 'Leader of Men' was a smash hit." Off the stage he was impressed by their industry and initiative in managing their career. Despite this, it still took Burman three months for him to convince his label bosses to approve the signing, a decision that would mark Roadrunner's first move into mainstream rock. Nickelback signed a record deal with EMI and Roadrunner Records in 1999.  The State, was released by Nickelback in 2000 by Roadrunner Records and EMI Canada. The State, was released in Europe in 2001. It spawned 4 singles: "Old Enough", "Worthy to Say", "Leader of Men" and "Breathe", the last two being Top 10 rock hits.
