Just found a broadcast on France Musique with the cello sonata by unsung French composer Joseph Boulnois (1884 - 1918). It's available on streaming (http://www.francemusique.fr/emission/le-concert-de-midi-et-demi-du-lundi-au-vendredi/2014-ete/autour-de-1914-partie-2-avec-marie-catherine-girod-antoine (http://www.francemusique.fr/emission/le-concert-de-midi-et-demi-du-lundi-au-vendredi/2014-ete/autour-de-1914-partie-2-avec-marie-catherine-girod-antoine)), with a piece by Georges Samazeuilh and Vierne's magnificent quintet, until September 7, 2014.
