Billy frequently writes music for his own projects and various large ensembles and has won the 2019 Eddie Harvey Jazz Arranger of the Year Award as well as both the small ensemble and big band category of the Dankworth Prize for Jazz Composition in 2016 and 2018 respectively. Most recently his composition 'Genmaicha'  was released by Patchwork Jazz Orchestra on their record 'The Light That Shines', recorded remotely during the Covid-19 pandemic. He wrote a suite for his octet inspired by gamelan for the 2016 Lancaster Youth Jazz Commission and his music has been broadcast on BBC Radio 3. In October 2018, Billy studied with Vince Mendoza at the Metropole Orkest Arrangers Workshop in Holland. His arrangement of Man in the Mirror was performed at the Lantaren Venster Rotterdam by the Metropole Orkest and New York based singer-songwriter Becca Stevens.

An alumnus of the Royal Academy of Music in London, Billy graduated with a first-class degree in jazz guitar performance in 2017. During this time he studied improvisation and composition with many UK and international jazz luminaries including Mike Walker, Pete Churchill and Barak Schmool. Billy is also involved in a range of music education work.
