The first single, "Days Go By" / "What We Do" was released in early November 2005. In October 2005, Barrett launched his own record label, The Contrast. On 9 January 2005, this Essential Mix was replayed on Radio 1 when another drum and bass artist, Andy C, was unable to deliver his mix. His mix included liquid funk mostly from the Hospital Records label. On 6 April 2003, High Contrast was featured on the BBC Radio 1 Essential Mix show.

In June 2002, Barrett's debut album, True Colours, was released on Hospital Records, with "Return of Forever" and "Global Love" finding their way into the UK Singles Chart. During his residency at Silent Running, Barrett played alongside artists such as Grooverider and London Elektricity. A short time after he began to make music, he was given a DJ residency at Cardiff's drum and bass night, named Silent Running. Barrett used to work in Cardiff's only electronic record shop, Catapult. Whilst studying film making in Newport, he heard J Majik's Arabian Nights which turned the then 17-year-old Barrett on to drum and bass music.

Barrett was born in Penarth, near Cardiff, and grew up more interested in films and film soundtracks than rock or pop music he cites Wendy Carlos's A Clockwork Orange soundtrack album and the Vangelis soundtrack for Blade Runner as defining musical influences.
