This article examines the ethical and poetic aims of sound use in the creation of Nous voilà rendus, a theatrical performance by the company L’eau du bain. The performance calls on the participation of elderly people with whom the artists of L’eau du bain create a theatrical event through a listening dispositive. If, for Blanchot (1955), writing breaks the bond that unites the word and the self, to listen might well be to lose ourselves within the world. “A promiscuity in listening puts into relief the abyss that separate us” writes Michaël Lachance (2015). This essay seeks to present L’eau du bain’s quest for a theatre that listens to listening in order to question and work through the relations between the inner and the outer worlds.
