Emanuel Ax, Leonidas Kavakos, and Yo-Yo Ma's new Beethoven for Three recording challenges the traditional boundary between chamber and orchestral repertoire to offer the listener two very different sides of the composer using the same three voices. In the C Minor piano trio, we hear Beethoven's brilliant exploration of three instruments' essential expressive capabilities; in the "Pastorale," lovingly reimagined for trio by Shai Wosner, the piano, violin, and cello transcend their own identities to represent the endless creativity of the natural world, becoming, in turn, bird, brook, and storm.
