Friedrich Kleinhapl and Andrea Woyke

As a memorable concert at the Austrian Cultural Forum and a series of recent CDs has made clear, Austrian cellist Friedrich Kleinhapl and pianist Andrea Woyke turn Beethoven staples into impetuous, seemingly spontaneous creations. You'll hear that approach in action this afternoon, and you'll also hear the duo tackle more-recent pieces by Rachmaninoff, Zemlinsky, Schnittke and Friedrich Gulda.
