«Derapage dans la ville» is an acousmatic composition for 8 speakers that reflects on the magnetic tape medium to create spatial sound images. The binaural soundscape emerges from the combinations of rhythms, textures, electronic instruments and voices, recorded and manipulated on tape loops. The piece focuses on the possibility for different sound objects to coexist autonomously in the space, to be teared of, to scratch, to hit or to merge together.
