Electroacoustic composer Robert Cahen studied at ORTF and CNSM in Paris under Pierre Shaeffer, turning to video work in the 1970s and applying musique concrete concepts to moving image, these compositions recorded at the GRM studios between 1971 and 1974 show his mastery over sound and his expressive ability to morph transitions through rich sonic detail.

Two works from French composer Luc Ferrari: "Music Promenade" (1964-69) an electroacoustic work for four stand-alone tape recorders presenting a series of colliding realistic sounds and sonic images; and "Unheimlich Schon" (1971), a quiet work of Musique concrete with spoken word--"How does a young woman breathe when thinking about something else?"
