One could blame the other boxes integral giving versions performed by musicians sometimes second zones. Here it is not so, the aeuvres are played by great pianists recognized: kissin, Rubinstein, Horowitz, cortot, etc ... The box is divided into two parts: 17 discs of recent records from 1970 to the present, and a dozen CDs of legendary pianists, dating a little more. Small flat compared to this, the sound quality of these archives is not always excellent. Place one of the first 17 drives, with crystal clear sound, a record 1930 may disappoint the listener. But the fault does not return to the editor that provides here a very beautiful box, where each disk is in a cardboard sleeve. The box comes with a well-filled book, I have not yet read completely, which includes a biography of Chopin and a lot of information on the package contents and pianists present on the records.
