Siôn Trefor is a composer, performer and producer based in the UK. His work is distinguishable by a fluid, staggeringly emotive musical language that is both highly distinctive and accessible.

Recent projects include scoring for a Netflix series and BBC Christmas special, and clients include Rolex, Aston Martin, Google Arts & Culture, Nationwide, Saatchi & Saatchi and the Sri Lankan government. Siôn’s closest and most constant collaborators include singer Charlotte Church and producer Young Rule.

Siôn will be releasing Stranger, his debut solo piano album in autumn this year, followed by A tergo lupi - a series of experimental electronic works with baritone Owain Browne.

Siôn will also be releasing material with his electro outfit, GXDS, as well as under the moniker Sionski throughout 2020.
