Born in Yokohama, Japan, Sauvage moved to Paris in 2003 after studying jazz piano in New York. She became interested in Indian music and studied improvisation of Hindustani music. Soon her desire of immersing herself in the water engendered the idea of using an underwater microphone and led to the birth of the electro-aquatic instrument. Under the form of performances, installations and musical compositions, her work is regularly presented in Europe, Asia and America. She has also been deeply connected to DIY art/music scene and is more and more interested in educational projects. In 2016, her visual music project Green Music started in collaboration with Francesco Cavaliere.
