Answer the question at the end by quoting:

Pendulum is an Australian drum and bass and electronic rock band founded in 2002. Pendulum originally formed in the city of Perth, Western Australia by Rob Swire, Gareth McGrillen, and Paul "El Hornet" Harding. The band was later expanded to include members, Ben Mount, Peredur ap Gwynedd, and KJ Sawka. Members Swire and McGrillen also formed the electro house duo Knife Party.
When Pendulum was formed, their musical style was considerably more drum and bass sounding than the work they were known for later in their career. Signature tunes such as "Masochist", "Vault", "Back 2 You" and "Voyager", which were released on labels such as Uprising Records, 31 Records, Renegade Hardware and Low Profile Records, have a darker, more amelodic air to them which is substantially absent from their later productions. The band's newer work is regarded as generally leaning heavily towards a mainstream, dance-driven sound. Early work such as "Another Planet" seems to indicate an early affinity with a more global sound, similar to other Breakbeat Kaos artists such as DJ Fresh and Adam F. The group has produced various remixes of other artists also; one of the best-known being the remix of "Voodoo People", originally by The Prodigy. In 2008-2010, they covered/remixed songs including Led Zeppelin's "Immigrant Song", Linkin Park's "The Catalyst", Calvin Harris's "I'm Not Alone", Coldplay's "Violet Hill", and Metallica's "Master of Puppets". Pendulum's versions of "I'm Not Alone" and "Master Of Puppets" both exist as studio recordings but have not been officially released, and are only previewed during DJ sets. The original live version of "Master of Puppets" was played as an instrumental introduction for "Slam", and was featured on their first live album/DVD. During their American tour as the supporting band for Linkin Park, the song was played in its entirety, with Rob doing vocals. Pendulum have also remixed their own music and, on occasion, television theme songs, such as Australian television's "ABC News Theme" in May 2010. The remix proved to be immensely popular with listeners of Australian youth radio station Triple J, polling at number 11 in the 2010 Triple J Hottest 100 countdown. Pendulum's musical style consisted of a fusion of drum and bass (along with other electronic genres), alternative rock and heavy metal, with the inclusion of acoustic instruments. This creates a sound reminiscent of electronic rock, albeit with much more prominent drum and bass and, more recently, dubstep influences. Some songs, such as "Slam", "Propane Nightmares" and "Witchcraft" are synth-led, whilst others, such as "Showdown", "The Tempest" and "Comprachicos", are guitar-led. Bassist Gareth McGrillen stated in an interview on Channel 4 that they use 13 computers during the live performances, all of which are mixing the sounds produced by the instruments in real time. Rob Swire stated in issues of TJECK magazine and Rock Sound magazine that he would like to begin producing songs with a punk style to them, which Gareth clarified to mean "A raw, aggressive, less polished method of producing". Pendulum were known to be fans of progressive rock and progressive metal bands, which may have inspired them to fuse multiple genres of music together, which is standard practice in those genres.

IN: 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.
