Many of his music works include an ethereal mixture of live sonic experimentation with grandiose classical motifs and alternative percussion.

Barker was classically trained at Newcastle University in the UK, and is a multi-instrumentalist, performing as a guitarist, percussionist, pianist and vocalist.

His first feature, Unhitched, a romantic comedy starring Seth Green, Stuart Townsend, and Amy Smart, was directed by Shooting Fish director Stefan Schwartz.

In 2007, Barker and Despic scored the $7m British ITV television production, The History of Mr Polly, starring Lee Evans; and in 2008, he continued his solo career, working with BAFTA-nominated director Martin Radich on the WARP Film and UKFC production Crack Willow, produced by Tristan Goligher.

They first met on the film Crack Willow and after Barker was asked to score his short, Five Miles Out and other projects after that.
