Pitchshifter are a British industrial rock/metal band originally hailing from Nottingham. The band was formed in 1989 by bassist Mark Clayden with guitarist and programmer Johnny Carter, later joined by vocalist JS Clayden and Stuart Toolin.

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.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.Their first few releases had a distinctive industrial sound where the influential gaze of Godflesh was abundantly apparent.The simplified 808 style drum tracks and sluggish drone guitars evolved over the next decade to produce some of the most intense loop based crunching metal/punk riffs and hard floor dance rhythm sections.

Throughout their highly acclaimed career although often commercially overlooked, Pitchshifter were often heralded with founding the Electro Punk genre with JS Claydon's 'sex pistols' barrages on the current state of the UK, simplistic chord driven guitar lines and the inclusion of more and more elaborate sampling and synth based elements.

Similar to previous attempts at this meld of minds such as Pop Will Eat Itself (PWEI) Pitchshifter created an intense and dedicated fan-base who still work hard to promote the outfit.Although the band officially ceased to be after releasing the album PSI, they have continued to reform for the occasional festival appearance or one-off event each of which is accompanied by one-off releases for ticket holders.

Since shutting down the PSI-political propaganda machine, members have gone on to work on various projects together and solo, including This is Menace, a super group comprising of members of Amen, Hundred Reasons, Funeral For a Friend and Earthone9.

Mark Claydon is now a regular tutor at the Brighton Institute of Modern Music (BIMM), and runs a regular advice column for bands just starting out in the UK-based Total Guitar magazine (available through Future Publishing).
