Collaboration with Charles Chemin. 20 Silences is a theatre piece and a musical work. A human being contemplates outer space. We witness his journey in time, and his conflicted interaction with the powerful environment that surrounds him. The soundscape, altered live by both the composer and an algorithm, enacts the impenetrable formation of galaxies, stars, planets, and the emergence of life forms. There is no such thing as an empty space or an empty time. A silence is a complex composition. Premiered at Babel Festival, Targoviste, Romania in 10 June 2017. Performed again at Conversazioni - 70° Teatro Olimpico Festival Vicenza, Italy.
