Belgian avantgarde singer born in Brussels in April 1955. Jauniaux began her career as an actress in Belgium at the age of 15. During the late 1970s and early 1980s, she sang with several experimental rock groups, including Aksak Maboul and The Work. In 1983 she teamed up with The Work's Tim Hodgkinson (ex-Henry Cow) in London to record her first solo album, Fluvial. In the early 1990s, Jauniaux moved to New York City where she became part of the Downtown music scene, performing with a number of musicians, including Fred Frith, Tom Cora, Marc Ribot, Zeena Parkins, Butch Morris and Ikue Mori. Jauniaux founded the duo Vibraslaps with Ikue Mori and later married Tom Cora. In 1995 Jauniaux and Cora moved to Southern France where she continued performing with various musicians, including Louis Sclavis, Heiner Goebbels, Otomo Yoshihide and Christian Marclay.
Jauniaux regularly works with artists in the field of dance and film, and sang in Heiner Goebbels's opera, Roemische Hunde in Frankfurt in 1991. She is inspired by traditional music, both real and imagined, and her performances mix seriousness and humour. She explores sound, emotion, melody and abstraction, and her vocal improvisations range from "traditional French chansons to breathy folk to Dadaistic glossolalia".
