The underground bunker next to the Centre Pompidou, set up in 1969 by the avant-garde composer Pierre Boulez to create electronic microtonal music for the new century, is looking less redundant nowadays with a full programme of courses and conferences. Not many concerts take place in the building itself, but IRCAM sponsors concerts with a modernist theme across the city. See the website for concert venues, and details of courses.
If you’re into technology, music and film, this spattering of addresses will tick your boxes - from cutting-edge cinema retrospectives at the Cinémathèque Française, to boundary-pushing digital art at the Gaïté-Lyrique.
