As a member of the Umlaut collective he is involved in the production, live or recorded, of various music: jazz, improvisation or contemporary composition and experimental music.

Founded from Jeanne Candel in 2009 to Paris, la vie brève is an ensemble in which actors, musicians, theater directors, set designers, costume designers, and technicians come together regularly for periods of research and creation. From its initial members, la vie brève has never stopped developing, transforming itself, reformulating itself according to the needs of the shows it proposes. It is the collective writing to that shapes the company's creations. The result is a polyphonic writing in which actors and/or the musicians and singers are placed at the center and are considered as creators and authors, not mere performers. la vie brève is particularly interested in the relationship between music and theater. The company stages music: live (most performers are musicians from from a jazz or classical background) or recorded, music is present in all performances. The main question we ask ourselves during rehearsals is: how do music and theater "weave the action" together at the same time; how do theater and music play together, play against each other, oppose each other, merge, and open a depth of field? This leads us to to experiment with various research processes and free forms from any dogma because they are rooted in the experience of the stage. The creations are made of various materials that make the boundaries of a performance flexible: pictorial, cinematic, scientific or philosophical materials, and the references are so many actorly bases that we invoke during improvisation or stage writing. from July 2019, la vie brève runs the Théâtre de l'Aquarium, which has become a house of creation for theater and music. "Twirling people around every corner" is the leitmotif. Associated artists, actors-musicians-singers, companies-in-residence work to make this instrument of resonance vibrate. Twice a year, in winter and spring, the company organizes the BRUIT - Festivals théâtre et musique.
