If you enjoy Moravec in Chopin (why wouldn't you?), I would recommend the 2002 release from Vox Classics (VXP 7908) on which he plays the Bb Minor sonata, the Berceuse, the Fantaisie, three mazurkas, and perhaps most importantly, his hands-down best recording of the 4th Ballade. So far as I know, there are three available recordings of Moravec playing the 4th Ballade. Of the three, this is definitely the best, and probably the best recording of the piece I have heard. (Another excellent recording of Moravec playing this piece is stuck at the end of the Supraphon release of the 24 Preludes).
And I would repeat the recommendations for his nocturnes -- unrivaled in my opinion. I have been on a Moravec kick as of late. Certainly one of the greatest living pianists.
As a side note, I've also recently discovered Earl Wild's Chopin. If you find Moravec's Ballades convincing, I have a feeling you may also enjoy Wild's recording of the Ballades and Scherzos... his interpretations are unlike Moravec's, but the two are similar in that they both fully/maturely understand the music and bring out all sorts of nuances many others miss.
Why do so few people know of Moravec?
