Music Promenade (1964–1969), 20'29

Electroacoustic Music World premiere for the Théâtre de la musique, March 16, 1970 «Hétéro-Concert»

Permanent version for four stand-alone tape recorders. A series of colliding realistic sounds and sonic images. Whilst walking, a man is struck by the violence of his surroundings. Nature has disappeared in a whirlwind of warfare and industry in the midst of which he encounters a dying folklore and a lost young girl. The "Installation" version is used to sonify a place in which walkers are free to choose their musical itinerary.
