Heavily influenced by Pink Floyd, discovered at 15, he is also inspired by the incredible keyboard player Jozef Dumoulin and the amazing NYC scene (Ben Wendel, Mark Guiliana, Taylor Eigsti).
Using rhythm as his main playground, Etienne develops in parallel a keen sense of melody while paying particular attention to sound processing.

In 2014, at age 19, he records his first demo as a leader with his open-fusion band EMQ. Since December 2016, Etienne is on tour with his trio, in a more acoustic mood, with a slight electric touch in the use of the Fender Rhodes. Their debut album Elastic Borders is out in February 2019.
In 2020, he created the duo Congé Spatial with saxophonist Pierre Lapprand. This duo quickly drawed attention, and their debut album is awaited in early 2023.

Aside from his activities in the jazz world, Etienne accompanies on a regular basis lyric singers. Among others, we can mention mezzo-soprano Aude Extrémo (ADAMI classical revelation), young baritone Philippe Estèphe (Cologne Opera, Opéra-Comique, Opéra Bastille), baroque ensemble Lyra and professional choir Dulci Jubilo.

Etienne is also passionate about writing and arranging for small and large ensembles. He is mainly influenced by jazz writers Kenny Wheeler, Maria Schneider or Dave Holland, and classical composers Claude Debussy and Maurice Ravel. He arranged for the big band "L'Autre Big Band", Montauban's music high school, and for many one-shot occasions.
