This is an excellent recording of this moving opera. Recorded in France in the late 50s, it features an entirely French cast. The sound quality is very good. The singing is excellent with nicely balanced orchestral work. The product partially of Poulenc's re-engagement with Christianity, Dialogues is the story of the martyrdom of a group of nuns during the French revolution. Characterized by deceptively simple, at times seemingly understated, music, Dialogues features lovely vocal writing married to a strong message about the value of faith. The final scene is a remarkable fusion of unaffected drama and music.
