Perahia does a masterful turn in the Pastorale sonata, arguably the focal point of this release, and also in the Sonata No. 10, which has always been one of my favorites as well. One other reviewer called the tone of the album a bit too refined, and I don't know that I'd argue with that, though it seems to me that that's perhaps more a criticism of the program itself rather than Perahia's playing -- all four sonatas on this album are on the prim side, after all. If you want more convulsive Beethoven keyboard playing, try other works that are that way to begin with. For refined Beethoven, this is very good stuff indeed.
