Some context: Def Leppard are an English rock band formed in 1977 in Sheffield as part of the new wave of British heavy metal movement. Since 1992, the band has consisted of Joe Elliott (lead vocals), Rick Savage (bass, backing vocals), Rick Allen (drums, backing vocals), Phil Collen (lead and rhythm guitar, backing vocals), and Vivian Campbell (rhythm and lead guitar, backing vocals). This is the band's longest lasting line-up. The band's strongest commercial success came between the early 1980s and the early 1990s.
Rick Savage, Tony Kenning, and Pete Willis, all students at Tapton School in Sheffield, South Yorkshire, formed a band called Atomic Mass in 1977. The band originally consisted of Willis on guitar, Savage on bass (after originally playing guitar), and Kenning on drums. Only 18 at the time, Joe Elliott tried out for the band as a guitarist following a chance meeting with Willis after missing a bus, in November 1977. During his audition it was decided that he was better suited to be the lead singer. Their first ever gig was in the dining hall in A Block in Westfield School in Mosborough, Sheffield.  The band adopted a name proposed by Elliott, "Deaf Leopard", which was originally a band name he thought up while writing reviews for imaginary rock bands in his English class (and in at least partial reference to Led Zeppelin). At Kenning's suggestion, the spelling was slightly modified in order to make the name seem less like that of a punk band. In January 1978, Steve Clark joined the band. According to Elliott, he successfully auditioned for the band by playing Lynyrd Skynyrd's "Free Bird" in its entirety.  In November, just prior to recording sessions for what would be a three-song release known as The Def Leppard E.P., Kenning abruptly left the band; he would later form the band Cairo. He was replaced for those sessions by Frank Noon. By the end of the month, Rick Allen, then only 15 years old, had joined the band as its full-time drummer. Sales of the EP soared after the track "Getcha Rocks Off" was given extensive airtime by renowned BBC Radio 1 DJ John Peel, considered at the time to be a champion of punk rock and new wave music.  Throughout 1979, the band developed a loyal following among British hard rock and heavy metal fans and were considered among the leaders of the new wave of British heavy metal movement. Their growing popularity led to a record deal with the major label Phonogram/Vertigo (Mercury Records in the US). Def Leppard's original management, MSB, a local duo consisting of Pete Martin and Frank Stuart-Brown, were fired after Martin and Joe Elliott got into a fistfight over an incident on the road. The band approached Peter Mensch of Leber-Krebs management, who had booked them on a tour of the UK supporting AC/DC. Mensch, who admitted that he had had his eye on the band, became their manager.

Some context: Fear Factory is an American heavy metal band that was formed in 1989. Throughout the band's career, they have released nine full-length albums and have evolved through a succession of styles, including nu metal, death metal, groove metal, and thrash metal. Fear Factory was enormously influential on the heavy metal scene in the mid-to-late 1990s. Fear Factory went on hold in March 2002 following some internal disputes, but re-formed a year later without founding member Dino Cazares, adding bassist Byron Stroud, and previous bassist Christian Olde Wolbers as guitarist.
In 1991, Fear Factory recorded a series of cuts for their debut album with the then-little-known producer Ross Robinson in Blackie Lawless' studio. The band's members were unhappy with the terms of their recording contract and caused a delay with the album's release. The band retained the rights to the songs, many of which they re-recorded in 1992 with a different producer, Colin Richardson, for inclusion on their debut release Soul of a New Machine. Meanwhile, Ross Robinson obtained the rights to the recording, which he used to promote himself as a producer. The album was officially released in 2002 by Roadrunner Records under the title Concrete after the band's breakup. The release was controversial because the album was issued because of the band's outstanding contractual obligation and without the approval of every band member.  Fan opinion has been divided as to whether Ross Robinson's production properly captured the intricacies of the band's sound. The released album favored a straight-up approach and Robinson's distinct drum sound. Concrete has become an important album for fans of the early Fear Factory sound; it can be seen as a bridge between the band's sound on their demo recordings and their debut release, Soul of a New Machine, and a blueprint for later songs and B-sides.  Based on the Concrete recording, Max Cavalera recommended Fear Factory to the then-death-metal-focused Roadrunner Records label, which offered the band a recording contract. While the band signed the contract, it has since become controversial because of Roadrunner's treatment of the band during the events surrounding its 2002 breakup. This was reflected in the first album Archetype (2004), which was released following the band's re-formation. The opening song with lyrics by Burton C. Bell, "Slave Labor", was direct about the band's feelings on the matter. After working with numerous bassists, Andrew Shives was hired as a live bassist prior to the release of Soul of a New Machine.
