Recording of Christian Zanési's Arkheion, les voix de Pierre Schaeffer. The composer has these remarks on the creation of this piece: In 1996, on the initiative of the Experimental Music Group of Bourges (GMEB), around a hundred composers paid tribute to Pierre Schaeffer. It was on this occasion that I composed a short, outdated waltz, the theme of which is childhood (it is said of Pierre Schaeffer that, when he was a few years old, he would have written a 'treatise on the hoop'). Later, I continued: the railway, the sound object, the single man, relativity in all things to evoke this multiple man who played with all registers and all voices. So many faces which, superimposed, draw a single form. As for Arkheion, the words of Stockhausen (1995) I composed this work from archives (from the Greek, arkheion). Karlheinz Stockhausen was a kind of distant and inaccessible angel, the ideal situation. I had only used one spoken document then. For Pierre Schaeffer, who is closer to me (I took his classes at the conservatory and produced several radio programs with him) I took, here and there, fragments discovered at random in the considerable mass of archives concerning him. With these fragments and the jumble of my memories, I simply wanted to express his look, both disillusioned and astonished (strange contradiction) in front of this experiment, still current, which he proposed in 1948: making music with recorded sound. Thanks to Michel Chion who warmly allowed me to use a few words said by Pierre Schaeffer in La temptation de saint Antoine. Thanks to Andréa Guinez whose bursts of laughter and voices sometimes accompany Pierre Schaeffer's remarks.
