2019 repress. "Alga Marghen very proudly presents the complete documentation of Eliane Radigues sound installations from 1969-1970. These previously unpublished recordings include the broad tectonic vibrations of Omnht, the celestial voices of Usral, Stress Osakas massive chant, and the moving horizon in Vice-Versa, Etc... The works of the feedback period finally revealed! It is amazing that she could build such formidably organic sonic edifices in her home studio with the primitive machines given to her by Pierre Henry: three tape recorders, a mixing board, an amplifier, two loudspeakers and a microphone. Eliane previously worked for him at the Studio dEssai of the R.T.F. from 1955 to 1957, after having met Pierre Schaeffer almost by chance, who invited her to learn the techniques of musique concr_ɬ®te. Created 10 years after her Studio dEssai experience, the Feedback Works of Eliane Radigue immediately take a new direction from the explorations of musique concr_ɬ®te. Her adventure is intuitively going toward flux, toward contemplative stasis: a music of continuous sounds, of apparently simple structures, which permits the revelations and expansion of rich acoustic phenomena. It is as if her musical work was in some way a martial art, as if she meditated for 10 years before striking the first blow, with an impressive precision! First pressing of 400 copies also including a 16-page LP-size booklet with original photos, scores and liner notes as well as a second LP titled Vice-Versa, Etc..., originally a small handmade box, signed and numbered, realized as a multiple on the occasion of a show at Lara Vincys gallery in 1970, which contained a reel of magnetic tape and the instructions for use. It indicates that all playback speeds are possible, forward or backward, as well as any combination of two channels, on several recorders, ad libitum... This LP presents two versions done by Emmanuel Hoelterbach following the indications of Eliane Radigue to the letter, respecting her composition methods." - Alga Marghen.
