Pitchshifter (originally Pitch Shifter) are an English industrial rock band from Nottingham, formed in 1989. The band was started by lead guitarist and programmer Johnny A. Carter, and bassist and vocalist Mark Clayden. The band's early material was characterized for its gritty industrial metal sound with downtuned guitars and the use of drum machines, and has been cited as one of the originators of the genre along with Godflesh. With later albums the group's music became increasingly more melodic and strongly influenced by nu metal and drum and bass; particularly evident of their 1998 release www.pitchshifter.com, which has been compared with groups like The Prodigy.

Although Pitchshifter has found little mainstream success, the band managed to gain a platinum certification with the release of the Mortal Kombat: Annihilation soundtrack. Since its formation, the band has released six studio albums, three EPs and eight music videos. The band has played in various festivals around the world including Ozzfest, Phoenix Festival and Damnation Festival.

Pitchshifter was formed in 1989 (initially spelled Pitch Shifter) by guitarist and programmer Johnny Carter and bassist Mark Clayden, later joined by Stu Toolin, and then Jon "JS" Clayden (Mark Clayden's brother). During this time, the band played with local bands and soon gained attention of the Peaceville Records. During this time, JS went to live in France to sell paintings.

They have cited major influences as Black Sabbath, Judas Priest, Metallica, Nine Inch Nails, Led Zeppelin, The Cure, The Doors, The Sex Pistols, The Ramones, and Ministry.^{[citation needed]}

During 1990, the band started recording their début album, Industrial, with the main vocalist being Mark Clayden instead of JS, who contributed with backing vocals. The band later went on a small tour with bands like Napalm Death.

The band later joined the British label Earache Records where they released their mini-album/EP Submit. Later, Stuart Toolin left the band, and the band hired Matt Godfrey to fill his place for some shows. Matt later left the band and they hired drummer D.J. Walters, now being a four-piece band. Later, the band released their second album, Desensitized.

The band played at the Phoenix Festival in Long Marston, England, in 1995. The band's manager, armed with a tractor, arranged for an enormous crop circle replica of the band's famous "eye" symbol to appear in the adjoining field to the festival site during the night prior to their performance there. The crowd's enthusiasm for the band when they performed was so high that they rushed the stage, making Pitchshifter's performance the first in the history of the festival to be stopped early.

The band later released the remix album The Remix War, which had appearances from other groups like Biohazard, Therapy? and Gunshot. The band then started working on the third album, Infotainment? and later played at the Dynamo Open Air. The band later left Earache and joined Geffen Records.
