Apparently starting off from a work for instrument-and-tape format, these pieces broaden the concept in several directions: the instrument featured is an early electronic one (ondes Martenot) and the electronic backcloth features a three-dimensional, spatialized character rendering the interaction between both far more complex. The compositions feature a sophisticated mixture of concerns ranging from concrete sources, sophisticated electronic textures exploring the legacy of acoustic sound masses of contemporary ascendancy and an original musical gesture, managing to orchestrate complex sound in a coherent whole.
