condition (record/cover): NM / NM Silver foil front, white back sleeve. Green labels. Voile D'Orphée I et II / Entité / Spirale exists in two copies in the catalog, same Philips number, presumably same cover. The veil of Orpheus separates visible from invisible, living from dead. Pierre Henry lifts it with his electroacoustic means, attempting to see beyond.
"Entité" and "Spirale" complete the program: entity as undefined presence, spiral as form that envelops and unfolds. Henry thought in mythological terms even when working with oscillators and magnetic tape. Technique always served vision, never the reverse. Two identical copies: the collector will choose whichever has the less worn sleeve. The music inside remains the same, which is to say, inexhaustible.
