*200 copies limited edition* A half-voiced sieve whose method is the title (Je me souviens de do dièse majeur dans un prélude en do majeur de Jean-Sébastien Bach), an impressionist loop that becomes a groovy construction (À mesure et au fur), a repetitive mechanic that fuses (Solar loops), rocket scales that color each other (La gamme qui teinte), an ecstatic, pulsating teenage cantabile (Morning song of the jungle sun), a harmonic march that traverses the keyboard, out of phase with itself (Les Charmes de la Marche) and, framing them, essences of themes like sonic mists through which light plays (Wind mosaics and Ville invisible): a portrait of composer, pianist and improviser Frédéric Lagnau (1967-2010). This is the first monographic disc devoted to him, in the spirit of a live album.
