The installation called Cet empêchement takes up a rather small, muffled space all in one piece.
A first speaker on a pedestal emits a voice: a little girl (litany of the hitches, closing, constraints). Farther away, two other speakers symmetrically set up on the floor and turned upwards open up a passage: music (a scaling motif that repeats itself like a tiny sequence to be, sharply stopped and endlessly taken back up).
