Appointed in 2011 as director of GMEM, the National Center for Musical Creation in Marseille, Christian Sebille serves in the dual roles of director and composer.

In 1983, he began focusing on electroacoustic music, which he studied with Jean Schwartz (Gennevilliers Conservatory) and Philippe Prévost (IRCAM); then, in 1987, he turned his attention to mixed media music as part of the Muse en Circuit group with Luc Ferrari.

In 1993, he founded Césaré in Reims, which became the National Center for Musical Creation in 2006; its artistic direction is focused on openness and the convergence of artistic disciplines and styles.

Christian Sebille’s catalog includes more than seventy vocal, instrumental, electroacoustic, and mixed-media works. Beginning in 1998, he developed a computer-based sound design approach that allowed him to explore the fields of improvisation and real-time performance both in France and abroad. (Alex Grillo, Philippe Foch, Matt Bourne, Miquèu Montanaro…). From 2002 to 2013, he created a large-scale series of musical installations titled Les 13 miniatures, in which he explored the concepts of space and landscape—elements that have since come to define and characterize his artistic practice.

Since 2009, a series titled *Les concerts radiophoniques* has featured live stage performances in which all electroacoustic elements (interviews, field recordings, real-time processing, sound effects) are combined with live musicians to create a live radio production. The most recent ones, created with Philippe Foch (percussion), established a dialogue between the two industrial sites of Donges (Pays de Loire) and Martigues (Étang de Berre). The latest was commissioned and presented as part of the DigitIZMir festival (Izmir, Turkey) in 2024.

Since 2018, Christian Sebille, an artist-in-residence at CIRVA (International Center for Research on Glass and Art), has been working on the project *Paysage de Propagations*, a series of projects that takes a wide variety of forms, including installations, performances, and concerts.

Since 2022, he has been creating a series of performance-based electronic works. The first was commissioned by the Chaillol Cultural Center (Le chant des cimes); the second, *Embrasser un arbre embrasserle temps* (2022–2025), is a landscape performance created in collaboration with choreographer Emmanuelle Huynh, in which the themes of landscape and space remain central.

In 2025, Christian Sebille composed*En voiture*, a *Musique-Fiction* (a series for an immersive sound installation—IRCAM-Centre Pompidou) based on an original text by Olivia Rosenthal.
