The first time I worked in the audio-visual was in 1982 when I composed the soundtrack for René Laloux's animated film « Les maîtres du temps ». Having to imagine unknown sonic landscapes and make them "plausible" was an uplifting experience. I came back to it a few years later with the same director and « Gandahar ». « Composed » sound has extraordinary expressive power and it seems to me that, today, the next continent to explore and exploit is precisely the territory of sound; whether that be in our immediate surroundings (signals, noises, controlled silences etc...) or in the imagined audio-visual. Compositional work in the sonic area can considerably revitalize the current musical landscape.
