Louis de Mieulle, born in Paris, began his musical journey at the age of 7, studying cello. He later transitioned to bass guitar, performing with the group Soundchaser, and earned degrees from the American School of Modern Music (ASMM), the Conservatoire National Supérieur de Musique (CNSM) in Paris (writing and composition), and the Berklee College of Music.
In the United States, Louis released a series of six instrumental albums blending jazz fusion and 1970s progressive rock. His projects featured renowned musicians such as Matt Garstka (Animals as Leaders), Casimir Liberski (piano), and Sarpay “SharpEye” Özçagatay (flute).
As a sideman, Louis has performed with a diverse array of artists, including Lulu Gainsbourg (pop), Casimir Liberski (electro-jazz), Sould’Out NYC (soul/funk), Peyton Pleninger (M-Base), Renato Diz (jazz trio), Nate Hook (avant-jazz), Uglybraine (hip-hop), Delsonido (electropical), Andrew Eckel (chamber pop), Yacouba Diabate (afrobeat), Mehdi Chaïb, Hamza Bencherif, Raphaël Pannier, Stéphane Galland, and Jean-Michel Pilc.
Remaining true to his classical roots, he won the Tours Composition Competition in 2006 with the opera Tres Para Una, co-written with Augustin d’Assignies and Edward Greaves.
Since returning to Europe, Louis has expanded into film scoring, electronic music (under the moniker Louison), and repetitive improvisation with his group Moonsüün.
