Barrett grew up more interested in films and film soundtracks rather than music, and still cites Wendy Carlos's A Clockwork Orange soundtrack album and the Vangelis soundtrack for Blade Runner as defining musical influences. 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 used to work in Cardiff's only electronic record shop, Catapult. 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. During his residency at Silent Running, Barrett played alongside artists such as Grooverider and London Elektricity.

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. His second album was High Society.
