During 1991 Mark Caro was based in [[Birmingham]], DJing at local [[UK hardcore]] parties. He soon started out on the production trail, with a very limited set up, producing [[hardcore techno]]. As his musical production skills and talent developed he released tracks as [[Ent. T]] through the [[Ibiza]] label. Introduced by a mutual friend, Mark soon formed a partnership with [[Darren Beale]]. As a duo they were moving away from the conventions of hardcore, following [[breakbeat]] into the less static realms of jungle. The pair's earliest tracks came toward the peak end of the [[UK hardcore]] scene; both Beale and Caro were noted DJs, with Beale's recorded work as [[Orca]] adding to his notoriety. They released, as [[Plasmic Life]], a self-titled EP, which appeared on [[Bizzy B]]'s [[Brain Records]].

Still only a part-time collaboration, further releases ensued, but their desire to run their own record label could not be quelled, and so [[Tech Itch Recordings]] was spawned. The label had limited success, which deepened after [[Omni Trio]]'s [[Rob Haigh]] heard [[Kenny Ken]] playing a selection of [[Technical Itch]] tracks on [[Kiss FM]], leading to their signing with Haigh's home-base [[Moving Shadow]] in 1996. Mark then relocated to [[Bristol]] from [[Birmingham]] where his production skills perfectly complemented Darren's musicianship as a guitarist. The pair produced a number of singles as [[Technical Itch]] for the label that same year, with scores of tracks as [[Decoder]] and [[TIC]] continuing to appear on their own and other labels, marking the pair one of the more prolific (and increasingly influential) of the new crop of jungle producers. Though a [[Decoder]] full-length was first out of the gate in late 1998, Tech Itch's Diagnostics followed in 1999 on [[Moving Shadow]].

With a prohibitively long list of aliases (Darren is better known as [[Decoder]] and is member of [[Kosheen]]) and strong links to [[Moving Shadow]], Tech Itch Recordings has been playing a major part in the worldwide jungle and [[drum and bass]] scene. Technical Itch is now widely known as being only Mark Caro, and his original tracks are widely renowned for their unique style, high level of production and programming, examples of which can be heard in recent releases such as The Rukus, Whrilwind, and Heavy Metal. With over 32 releases on the Tech Itch label and a new sister set-up entitled [[Penetration]], Mark and Darren's presence within the [[drum and bass]] scene is ever-stronger. In 2004 [[Technical Itch]] merged his [[Tech Itch Recordings]] with [[Dylan]]'s [[Freak Recordings]] to create [[Tech Freak Recordings]]. The natural progression has led to long-term projects with [[MC Jakes]], [[Dieselboy]], [[Kemal]], and a long list of others who compliment their unique style of music. 

In 2006, Caro began releasing [[dubstep]] recordings under the name Tech Itch.
