The octet version of "les instances" is projecting an electrified sound world emerging from the musical synergies and the coexistence of an amplified ensemble with a synthesized, electronic soundscape. A continuum of interchangeable drives it, phrasal collages comprised of distinct sonic and rhythmical structures, both in the acoustic and the electronic parts. The structure is formulated by repetitive blocks and timbral constructs that engage horizontally and vertically (harmonically) and eventually forge the behavior and the dramaturgy of the music. At the core of my creative thinking lies the notion of repetitive exhaustion and dissolution of sonic material in frameworks of organic sound complexity. I am deeply interested in the impact of recursion on our perception of details and musical events at a micro and macro time level. The piece is heartily dedicated to George E. Lewis.
