List of experimental music festivals

Experimental music is a compositional tradition that arose in the mid-20th century, particularly in North America, of music composed in such a way that its outcome is unforeseeable. The Groupe de Recherches de Musique Concrète (GRMC), under the leadership of Pierre Schaeffer, organized the First International Decade of Experimental Music between 8 and 18 June 1953, and the phrase was used by musician John Cage as early as 1955. Afterwards saw the development of specific experimental musical instruments, which were featured at various music festivals. Musique concrète is an experimental form of electroacoustic music, and free improvisation or free music is improvised music without any rules beyond the taste or inclination of the musician(s) involved.
