Tristan Cassel-Delavois is a musician, composer and producer based in London.

Having studied the violin from an early age, Tristan moved to learning the guitar on which he began to write and record songs for himself and others from the age of 15.  After completing a Bachelors degree in Popular Music Performance at the Guitar Institute he continued writing and performing his own music in several bands in London.  His experience as a live musician combined with his knowledge of music-technology  led to him being picked to play, tour and record with artists including Tricky and Tim Minchin from 2008 to 2014.  

As more live shows started using laptops and computers Tristan taught himself to both use and custom program Ableton Live. And in 2012 he programmed the  Tricky live show seamlessly recreating Tricky’s seminal album Maxinquaye using original samples and sampled loops of the 1995 recording enabling the truest “live” performance of the album since its original conception.

In 2014 drawing from the experience of programming live shows and directing bands, working with backing tracks, drum loops and more recently with string and brass sections, Tristan started to compose for picture.  The first projects included BFI Film London Short - Two Seas (selected for screening at the BFI London Film festival) and commercial/branded projects for Lexus and Youtube/Comic relief.

Currently, Tristan is composing for the follow up film to Two Seas shooting later this year as well as the debut feature film written and directed by another BFI Film London short film director Sarmad Massud.

Live projects currently include Leftfield, Francesca Belmonte and Bear Nang.
