I seem to remember some of the orchestral songs being poorly/unattractively sung, but the "Flute, harp & strings" CD is one of my favorite French music CDs ever, and a lot of the orchestral music is very attractive. Maybe derivative of Debussy, but derivative in a way that is still good and enjoyable.
I've heard the cello sonata, piano trio, and piano quintet, but can't remember my impressions. Maybe time to listen again.
EDIT: Oh hey I talked about the cello sonata earlier in the thread. And those CD covers are still the best.
