prospective 21° siècle

Prospective 21e siècle which was launched in 1967, quickly won its place as the most avant-garde, the most revolutionary of all record collections: "revolutionary" in its presentation (metallized record sleeves in keeping with their contents), in its exclusive repertory - concrete, electronic and experimental music - and in its price, putting it within the reach of all, and especially of young people, who are passionately interested in new sonic effects.
