I agree with you that this set has some interest. In addition to Debussy's influence (and I could be way off-base here, having never heard of Grovlez before), I seem to hear hints of Grieg (Lyric Pieces) and maybe even Dvorak, what with the drone basses and rustic, dancing rhythms (in certain pieces, e.g., No. 4). Interesting that the Berceuse de la Poupee differs from the title in the Children's Corner set by only one word, although that word makes all the difference for the piece's character
My only real complaint with the music is that it sometimes lacks tautness and structural integrity, meandering discursively from section to section. But it more than makes up for that with its pleasing impressionistic sonorities and eclectic incorporation of various influences (at least so it seems to me).
Your playing of these pieces seems generally well phrased and controlled. You seem to have a feel for the slow, lyrical pieces in particular. These are also IMHO more polished than some of your earlier recordings. My only advice would be to sometimes give the technical side a bit more work. It was mostly clean and clear, but there were a few passages in which the rhythm sounded a bit awkward or the fingerwork a bit enjambed. Some things I noted about specific pieces:
1. Nice jaunty rhythm at the outset. The left hand seemed soupy in a couple of places near the beginning.
2. Very well played, sensitively phrased and nice ritard to end.
3. Good singing line. The double-note unison passage somewhere in the middle seemed as though it could be more precise (also hands not quite together).
4. Again, overall rhythm could be tauter IMO, seems as though maybe the overall tempo could be a tad faster and livelier. I like the element of surprise in your ending.
5. I like your sound and balance very much here. The underlying rhythmic pulse seems just a little bit flabby to my ears (maybe some of the accents could be a bit more mordant). I have to say I have a soft spot for these bucolic character pieces (these aren't in the league of those in the Liszt Annees, but they're pretty convincing).
6. Very elegant touch. Nice glissando-like effects. Nothing really to complain about on this one.
7. Wow, talk about a mercurial change in mood! The Viennese waltz theme is immediately apparent. This one seemed a bit overpedaled in places, and maybe a few slipped notes; nothing major though. Overall it could perhaps have more lilt and charm.
8. Nice and introspectively played. Again nice sound and well-employed rubato.
But not to nitpick too much. Very nice work on these in general. Thanks for introducing us to this music.
