He produces drum and bass music, and his 2009 album Confidential reached BPI gold certification (100,000 units sold in the UK).

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.

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.

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.

He also made successful remixes of "Hometown Glory" by Adele and "Pjanoo" by Eric Prydz, which were later included on the album, Confidential.

High Contrast played a key role in selecting and producing the music for the Athletes Parade at the 2012 Summer Olympics opening ceremony.

A double release, 'Part 2'[4] was Special Delivery on Annie Mac's BBC Radio 1 show,[5] followed by 'Part 1'[6] as "Hottest Record in the World" for Zane Lowe.
