aised listening to acts like Crass and Flux Of Pink Indians, brothers Mark MD Clayden (bass) and Johnathan JS Clayden (vocals) decided to create their own doom laden Industrial Metal act in the style of Ministry and Godflesh. The original drummerless line-up would also feature Stuart Toolin (guitar) and Johnathan JA Carter (guitar/programming) to release their debut Industrial (1991) on the 'Peaceville', label and would soon join 'Earache' with the mini set Submit following a year later. Although electronics aided their sound they nonetheless hired a full time human drummer under the name of D. Crushing (a.k.a. D.J. Walters). Desensitized followed in 1993 much in the same style as their past works. But their electronic influences would force a remix album in 1994 titled Pitchshifter -Vs- Biohazard - Therapy? - Gunshot (The Remix Wars). That album was followed up with more of their traditional ear shredding demonstrations in the form of Infotainment? (1996). They had yet to achieve the notoriety of their peers but the Genius Making Plans For Nigel single in 1998, now featuring Jim Davis on guitar, replacing Toolin, set that right with a 71 in the UK now on the 'Geffin' label.
Their attempts at getting upgraded to the internet revolution failed to chart them at www.pitchshifter.com (1998) by yielding only one hit, Microwaved, when spun off as a single, making 54 UK; its flipside sporting a remix of Genius. The EP Un-United Kingdom (1998) saw them with just Davis and the Clayden brothers, but chart success was met again with Deviant (2000) proving to be their first album to chart at 35 UK and now on 'M.C.A.'
Those who listened to Pitchshifter out of context noted that their earlier albums of heavy guitar work were a stark contrast to their later work featuring sampling and electronic influences, but listening to their albums over their career the style changes were much more subtle as each album came and went. After their 2002 release of P.S.I. Jason Bowld joined on drums but after their March 2003 UK tour the act decided to call it quits with an amicable split of the members choosing to pursue other interests.
