Musique concrète
The Bay Area Improv Scene is a commonly used name for a loose association of musicians and composers centered in the San Francisco Bay Area who create a style of music that evolved largely from avant-garde jazz and modern classical music, with influences from other areas such as Electronic art music, Free improvisation, and Musique concrète. Other names of this scene tend to use phrases such as "Creative Music" to try to incorporate a wider focus than just the improvisational approach.
