Paul Lewis's traversal of the Beethoven Piano Sonatas may just become one of the indispensable recorded versions of these unique works. He tackles the Hammerklavier without attacking it; his interest is textual clarity, and he never fails in that approach. If you listen to the last movement of No. 25, "Alla tedesco," you'll be amazed by the formality and forward propulsion which underpins the seeming merriment in the piece, the abrupt ending suddenly quite a puzzle. Similarly, the first movement of the Waldstein is imbued with a darkness that makes you think you're hearing much of it for the first time. Lewis's is a serious--some might say grave--approach to these works, but it is not heavy; indeed, his touch remains light when it ought to be, without making the music seem trivial. Each movement lets us in on another one of Beethoven's secrets, and the lyrical moments have never seemed lovelier. This is a very special set, highly recommended. --Robert Levine
