Take thirty years of sound creation by Kristoff K.Roll, an electroacoustic music duo that loves to make the hum of the world heard, break down boundaries, defend the enriching power of creolization, and open the door to dreams… Take a human sciences researcher, Pierre Johan Laffitte, a language specialist: What analysis does he bring to their practice and poetic language? Alternating musical moments, videos of the duo, and theoretical reflections, this illustrated conference will offer a retrospective, offbeat, transversal, and critical perspective.
