Eliane Radigue’s complete Opus 17 (1970), her finest and final work created using feedback, is contained on this double CD. With Opus 17, Radigue perfected her slow mixing technique with sublime results. Imperceptible transformations envelop the attentive listener who is confronted with an immensely physical experience. Time is suspended in powerfully poetic and artful ways as Radigue masterfully sculpts the physical matter of sound using feedback for the last time. Opus 17 is an absolutely essential masterpiece in the realm of early electro-acoustic/drone/minimalist composition.
