This set doesn't include all of Chopin's piano music because Artur Rubinstein didn't record all of it. (The Etudes are the most notable omission.) But it does include the last, and usually best, versions of all the Chopin he did record, along with three earlier versions. Other pianists have had other things to say about Chopin, and it's a mistake to think that any one performer can give you the complete picture of any music. But these performances, for the most part, are as good as we've come to think they are, so at mid-price this 11-disc set is a real bargain for Chopin lovers. --Leslie Gerber
