The legendary pianist Mitsuko Uchida played Hertz Hall for the first time in 10 years Tuesday. The first part of the program was Schubert's Sonata in G Major Opus 78. Alternating between gentle pastoral motifs and fortissimo power chords, Uchida is a virtuoso of the highest order. The music breathes through her; she becomes one with the composer. The second work was Beethoven's Thirty-Three Variations on a Waltz by Anton Diabelli. Again the dynamic contrast was extremely dramatic, from whispers to heroic explosions. From satire to pathos to patriotic hymns to sublime reflection. Angleic in Matsudo silk pants and cape, Uchida has an amazing vitality and energy for such a mature artist. I was reminded of Arturo Benedetti Michelangeli.
