Radia Show 408: “Bloop” by Claire Serres for Radio Campus Bruxelles. Radia is an international network of radio stations interested in new and forgotten ways of making radio art. Each week a different station takes a turn creating a show for all the others. The Bloop is a submerged frequency, it diffuses in depth. Can you capture it ? I catch it, play again again. In her work, Claire Serres uses microphones and vocal attacks to detect the origin of Bloop.
