1972 split release on Pathé Marconi EMI by the GMEB - Groupe de musique expérimentale de Bourges - founders & wife-and-husband team of Françoise Barrière & Christian Clozier. This is the first issue of Barrière's work & only the second of Clozier's after the Perspectives Musicales "Lettre À Une Demoiselle / Dichotomie / Petite Suite / D'Une Multitude En Fête" split w/ Jacques Lejeune (Creel Pone #073). Barrière's three-part "Cordes-Ci, Cordes-Ça" coats the A-side, electronically warping her Harpsichord stylings , Violin playing by Clozier, & contact-mic'ed Hurdy-Gurdy by the Swiss musician Rene Zosso - responsible for the fantastic Le Chante du Monde LP "Chante & Vielle" & the collaborative Harmonia Mundi duo LP with Anne Osnowycz, "Musique A Bourdon" from a decade later - into a master-stroke of Musique Concrète. Similarly, Clozier's seven-part suite "La Discordatura" treats clipped solo & ensemble playing to studio processing ranging from subtle, almost imperceptible edits & pitch-extensions to full-bore re-synthesis & scatter. Along with "Lettre À Une Demoiselle" & "Dichotomie" this piece forms the center of his early work.
