Voir sur FrenchStream. In this vivid transposition of contemporary music for television, Cahen "responds" to the complex musical transitions of Répons, a work by French composer Pierre Boulez. Performed by the Ensemble InterContemporain and conducted by Boulez, the intricate Répons was designed for an ensemble of twenty-four musicians, six soloists and a "real-time" digital processor. In Cahen's re-composed interpretation, he responds with visual and temporal transformations, "opening" the images in space and time and applying electronic techniques to engulf the instrumentalists in ocean, sky, and trees. Mirage-like superimpositions, temporal shifts, mirroring effects and de-synchronization result in a rhythmic confluence of the illusory and the real. Immersing the viewer in image and sound, Cahen mirrors the transformative process of Boulez's music.
