The French musicologist Michel Arcens gently included my "Musica invisible" in one chapter of his beautiful book «John Coltrane, la musique sans raison».He made a poetic interpretation of my music connected with John Coltrane's. The book was just released, en français. The presentation is 12th Octoberin Librairie Torcatis, rue Mailly à Perpignan. Merci beaucoup, Michel!
