Regarding the chamber music I have the DECCA recording with Pascal Rogé (piano), Gallois (flute), Bourgue (oboe), Portal (clarinet). It is very good, fresh and natural, with Rogé at his best.
Regarding the choral music I think that the best recording is the one of the Groupe Vocal de France conducted by John Alldis. The 4 Motets pour le temps de Noel are delightful.
