Of Les Six you can delete Durey and Tailleferre (sp?), leaving Les Quatre: Poulenc, Milhaud, Honegger, and Auric. Poulenc is probably the most tuneful. I have a recording of the Gloria and the Organ Concerto that I like for melody and vigor. Milhaud's Suites Francais and Provencale are fun. The aforementioned Creation of the World is very exciting. I also have an old recording of his percussion concerto. Great beginning. Honegger's claim to fame is Pacific 231. That's a grabber. If you ever get a chance to see the film by that title that was cut to the music (in spite of the ancient sound), it's an experience. I've also been listening to and enjoying his Judith and King David (choral works with narrator). Auric's popularity rested on the "Song from Moulin Rouge". I have not heard much else of his. Maybe Les Six are by now Les Trois. As for Satie, a kindred spirit, and "model"(?) for Les Six, Only the Gymnopedies stand out from the rest to me. They are magical. Many of his titles are more amusing than the works themselves. His wit makes him immortal. For example, when asked what part of Debussy's La Mer he liked best, he answered "oh, about quarter of twelve". Of course you have to know the section titles to appreciate that. Part 1 is titled "From Dawn to Noon on the Sea".
