This interpretation of Saint-Saens III symphony enjoys a reference status according to many critics. So I decided to check it out, although I am not a fan of Charles Munch. My overall impression is positive: the BSO orchestra plays very well, the dynamics are wide enough. I enjoyed the details and expression of the soli and the "singing" of the piano and pianissimo parts. However, this is not my favorite execution. For my taste the high volume/voltage moments are not too nitid, both in terms of tempi and expression, so many climaxes result somewhat blurred, which spoils the expectations built (well) from the softer parts. My recommendations among "old" recordings would go to that conducted by Paul Paray, if not to the Toscanini interpretation (here the quality of the recording probably demands too much from the listener...). Similar considerations apply also to the other pieces in the SACD.
