I was reading a book on twentieth century music (although it was written in the middle of the century, so it's a little heavy on the first half) and the author was quite enthusiastic about the piano music of Dukas, music I didn't even know existed. So I ordered the CD and have listened quite a few times. The sonata is quite large and complex so of course it took a few hearings. I find all of his piano music worthwhile. There are no surprises: it's late romantic and French. I often buy CD's of forgotten music and am disappointed, but I wasn't disappointed here.
