Born in Valréas Vaucluse, Chevillon followed a double training since he graduated from the Beaux Arts in 1983 where he studied photography, and at the same time followed Joseph Fabre's classical double bass teaching at the Conservatoire à rayonnement régional d'Avignon [fr].
He made his debut in jazz by following the class of André Jaume [fr], is a member of the Groupe de recherche et d'improvisation musicales (GRIM), then joined the Lyon collective Association à la Recherche d'un Folklore Imaginaire [fr] where he made a decisive encounter: that of Louis Sclavis.
[1] In addition to his long collaboration with Sclavis, the double bassist plays with the main actors of avant-garde jazz and Free improvisation : Marc Ducret, Claude Barthélemy, Stéphan Oliva, François Corneloup, François Raulin, Joey Baron, Elliott Sharp, Franck Vigroux, Benjamin de la Fuente, Samuel Sighicelli, Laurent Dehors, Gerome Nox etc.
[2][3] Essentially a sideman, Chevillon also flourishes as a soloist, however, notably in his performance on Pier Paolo Pasolini.
[4] In 2007, he recorded his only solo album Hors-Champ published on the label d'Autres Cordes, which mixes double bass and electronics.
