A major work in François Bayle’s repertoire, »Jeîta ou murmure des eaux« provides a journey and an immersion into a world of unleashed energies, with the Jeîta cave serving both as a backdrop and a particle accelerator. Here, the cave indeed stands for the concrete source of the composer’s inspiration as much as the mind space where metamorphoses occur. By combining such figurative spaces and immaterial sound projections, François Bayle evokes another subject, an inhabitant of the multiple and symbolic cave: the listening subject, who always reveals himself, implicitly, at the heart of François Bayle’s musical concerns and the path he has always defended: the acousmatic approach.
