Assembled from live recordings made over many years, this is a Beethoven program from one of the great Russian pianists of our age. The wunderkind has turned into a thoughtful, intellectually probing player who has found new meanings and messages in these often-familiar works. Popular nicknamed sonatas like “Moonlight,” “Appassionata,” and “Les Adieux” sit alongside Beethoven’s towering 32 Variations on an Original Theme and his visionary last sonata, and Kissin gives masterly accounts.
