“One act, one room, one character, love, and the banal accessory of modern plays, the telephone.” This is how Cocteau described his play La Voix humaine, set to music by Poulenc in 1959. The haunting monologue of a woman on the edge, where emotions – hers and ours – race by at lightning speed. The role of a lifetime, embodied by the incandescent Patricia Petibon.
