Sur Le Temps brings together Ensemble Batida, a contemporary trio of percussionists (Alexandra Bellon, Anne Briset, Jeanne Larrouturou), and the vocal quartet Contre le Temps, whose female voices specialise in medieval repertoire. The programme juxtaposes organum with open improvisation, exploring the distance between a centuries‑old vocal practice and an intensified attention to the present. The first part presents organum; later the musicians engage in improvised encounters that blur historical and contemporary sound worlds.

The project is organised by Ensemble Vide, an interdisciplinary platform for contemporary music and artistic research.
