Founded in 2011 at the instigation of Frédéric Blondy, ONCEIM is an orchestra of 34 musicians and a collective which assembles their various projects.

ONCEIM is dedicated to contemporary creation in an approach to sound as a plastic art form, by experimenting a number of different modes of musical elaboration, transmission and composition. In this work process, each musician has a major creative role, constructing the music through their singular virtuosity and the musical vocabulary they devise through their instrument.

ONCEIM brings together very high-level instrumentalists who develop their own completely personal instrumental practices and music styles. They are performers and/or improvisers and/or composers, and often all three at once, which allows them to fully grasp the complexities and subtleties of the music of today.

ONCEIM has been in residency since 2011 at the Saint Merry Church (Paris) and is supported by the National Centre for Musical Creation – La Muse en Circuit, the City of Paris, the French Institute, the ONDA (French office for contemporary performing arts circulation), the SACEM (Society of Authors, Composers and Publishers of Music), the FCM (Musical Creation Fund), the SPEDIDAM (Society for the Collection and Distribution of Royalties for Performing Artists) and the Regional Office of Cultural Affairs of Ile de France – Ministry of Culture and Communication.

Thanks to this support, the orchestra has played in Europe in Xavier Veilhan’s Studio Venezia at the Venice Biennale, at the Sacrum Profanum festival in Krakow, the Edition Festival in Stockholm, Mozg in Bydgoszcs, VinterJazz in Copenhagen, the Insub festival in Geneva as well as at festivals in France such as Météo, Densités, Extension, and at institutions such as the Théâtre d’Orléans, the Macval and the Fondation Cartier.

ONCEIM is directed by an artistic committee composed of Frédéric Blondy and of 6 musicians (elected every two years): Félicie Bazelaire, Jean Dousteyssier, Benjamin Duboc, Jean-Sébastien Mariage, Frédéric Marty and Julia Robert. It is administrated by Eglantine de Boissieu via the Babbel association (
