Celestin Deliège, recently deceased, was the last representative (with Pierre Boulez) of post war modernism. Prestigious musicologist (passing his encyclopedic knowledge through violent polemic), teacher at the Conservatory of Liege, Brussels and la Sorbonne, he impressed many students students who become important composers of today, not least Hughes Dufourt, a founder of spectral music. This film is made from ten meetings filmed (introspective face to face or with Decroupet Pascal, Francois Nicolas, Fred Lerdahl, Hugues Dufourt, Antoine Bonnet and Ensemble Ictus.) shows a man in his illness, certainly, but who fights until the last breath, looking for a lost transcandence, a re-enchantment, calling for Artaud's madness ... Rooted in suprême art of music, it leads to pain departure and beauty to exist.
