The French musicologist Michel Arcens gently included my “Música invisible” in one chapter of his 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, in French. The presentation is 12th October in Librairie Torcatis, rue Mailly à Perpignan. Merci beaucoup, Michel!
