The Groupe de Recherches Musicales (GRM), founded in 1958 by Pierre Schaeffer, is a pioneering institution in electroacoustic music. Emerging from the earlier Groupe de Recherche de Musique Concrète, the GRM became a hub for avant-garde composers like Pierre Henry, Luc Ferrari, and Bernard Parmegiani. Dedicated to exploring and expanding the boundaries of sound, the GRM has significantly influenced the development of musique concrète and acousmatic music. Now part of the Institut National de l'Audiovisuel (INA), the GRM continues to be a leading force in sound experimentation and preservation.
