The Cinematic Orchestra is a British-based jazz and electronic outfit, created in the late 1990s by Jason Swinscoe. The band is signed to Ninja Tune independent record label. In addition to Swinscoe, the band includes former DJ Food member, PC (Patrick Carpenter) on turntables, saxophonist / pianist Tom Chant and bassist Phil France. Former members include Luke Flowers (drums), Jamie Coleman (trumpet), T. Daniel Howard (drums) and Alex James (piano). The latest member of the band is guitarist Stuart McCallum. Stuart hails from Manchester and provides a further creative force in an already highly original band.
