« Labyrinthe ! » (2003), 56'41Premiered on March 29th 2003, salle Olivier Messiaen de Radio France, Paris. Commissioned by Radio France.An expedition in sound in 10 sequences: Enfoncement [Deep Sink], Gouffre circulaire [Circular Abyss], Noyau secret [Secret Core], Apesanteur [Weightlessness], Entrailles [Entrails], Four solaire [Solar Furnace], Fissures [Cracks], Mer intérieure [Inner Sea], Éruption [Eruption], Remontée [Ascension].Labyrinthe ! is not only a very unique piece in Pierre Henry's masterful repertoire, but also a remarkable demonstration of his compositional skills and musical singularity. Indeed, for this piece, Pierre Henry was deprived of his own, otherwise essential, sonic material. Here, the sounds, provided by GRM collaborators at the time, carry their own distinct stories, sensitivities and qualities. Yet, despite this discrepancy, Pierre Henry's voice, the breath and dynamics of his own music, quickly appear. Through this sonic maze, a music arises, utterly focused on sounds, their development and their use, which Pierre Henry applies with extraordinary clarity and determination.François J.
