For folks interested in listening to more of his compositions Spotify has recordings by JMR himself and by Cyrloud. They are close friends and Cyrloud is a wonderful player. Worth checking out both to hear the range of compositional skill JMR possesses.
Bernard Cyrloud (who is a cardiologist in his day job) has made two full CDs of Jean-Marie's music, available through Les Productions d'Oz. Really nice discs. He also has a number of YT videos so you can see him playing these as well.
