July 2025;  long in the queue (at least as long as the C.P. replications of Jean-Claude Eloy's two outings early in the series) has been this pairing of the other two CP-adjacent Erato titles by the GRM Composers Guy Reibel & François-Bernard Mâche.

Starting with 1969's "À Mille Et Une Voix" on Disc 1, the three pieces ("Carnaval for one actor, three choirs & tape from a text by Roger Marty", "Trois pièces de rumeurs (échappée-bloc choral-continuo) for seven soloists, two choirs, six chorales masses & tape", & finally "Durboth for soprano, chamber orchestra & tape") feature Reibel's earliest works for ensemble with meshed Tape backing as played by a who's who of the Mai '68 Avant Garde: Rainer Boesch, Arlette Sibon-Simonovitch (absolutely RIPPING on Ondes Martenot throughout), Jean-Pierre Drouet, Gérard Fremy, Marius Constant & Ensemble Ars Nova, etc.

On Disc 2 covering Mâche's Kemit, Korwar, Temes Nevinbür, Canzone II, the four pieces for Solo Percussion (as played, again, by Drouet), Harpsichord & Tape (ditto, Elisabeth Chojnacka), Two Pianos, Percussion, & Tape (Drouet w/ Katia & Marielle Labèque) & finally Wind Quinet all seamlessly blend deftly assembled Concrète with virtuosic performances that border on the unreal. Both come inside the familiar 6-panel semi-gloss booklet, with the addition of a reconstruction of the chronologically-appropriate 1969 Erato promotional booklet as a separate insert.
