If someone put a gun to my head and demanded to know the best choice for a Chopin cd purchase, I would state with confidence "get the EMI classics Rubinstein collection". These recordings, made mostly in the 30s, contain some of the very best Chopin ever recorded. I've spent a lot of effort trying to find definitive versions of every Chopin piece, with the result that the Rubinstein 30s recordings of the Concertos, Nocturnes, Mazurkas (which are contained in the present set) are historically definitive. For competitors, I mention Moravec's 60s recording of the Nocturnes and Zimerman's two recordings of the concertos. I know of no better recording of the complete Mazurkas. Also, no Chopin fan should be without the present recordings of the Scherzi and Polonaises, which have few competitors. For the Barcarolle I suggest Dinu Lipatti, and for the Berceuse, Solomon. But each recording here, definitive or not, is first rate and a front runner. The recordings were made at the beginning of a transition period Rubinstein made in his 40s when he forced himself to relearn his repertiore in a more disciplined manner than he had previously; it was at this stage in his life that Rubinstein acquired the status of being one of the greatest piano artists of the century. Thus these recordings are very inspired and more reliable than later Chopin recordings he made. Of course Rubinstein is, over all pianists, most closely associated with Chopin. This is somewhat unfair in the sense that there are many brilliant pianists who have outstanding recordings of Chopin which do compare and sometimes exceed Rubinstein's. The present set is an outstanding selection which will best represent Rubinstein's contribution to a library of Chopin recordings.
