Ars Subtilior (14th Century) and the Noise: the two inspirations of Christophe Guiraud which are like two rivers which are woven in a writing of great power. The young French composer is the link between the most accomplished scholarly music and some radical aspects of noise. Born in Toulouse mid-seventies, he settles in Brussels -- which becomes the crossroads of a continuous creation. He currently works and has been collaborating since several years with numerous European ensembles and musicians such as Ensemble Ictus, Phønix16, Tom Pauwels, Timo Kreuser, Ensemble 21, Sturm und Klang. His most recent pieces intimately mix instrumental timbre and sound hybridization, cultivating a certain secrecy around this alchemy. On Kutra Bégulma * Unfinished Altar more than everywhere else, Christophe Guiraud's compositions create a dialog between the times, from the polyphony of Ars Nova to Spectralism, while integrating his noise heritage. Resolutely an-historical, the last pieces presented here unfold in a trembling stagnation. The ensemble of the pieces creates coherence across a wide range of musicians coming from different places and traditions and from different ensembles -- everything is woven together towards a rather spectacular conclusion: Tarentule Ensemble (Paris), Phønix 16 Ensemble (Berlin), Laps Ensemble (Brussels) with the support of Bernard Sberro (Tel Aviv), Julien Boutonnier (Toulouse) Pauline Claes (Brussels), Jessica Constable (London), and Iris Terdjiman (Napoli).
