Two multi-year projects will also be launched that concentrate on the work of a single composer: Beethoven with Norwegian pianist Leif Ove Andsnes; and the Bach Keyboard Cycle, which marks the beginning of pianist András Schiff’s two-year examination of Bach’s keyboard music. Other celebrated artists featurted in the season’s programming include violinists Itzhak Perlman and Hilary Hahn; pianists Hélène Grimaud, Yefim Bronfman and Yuja Wang; and vocalists Renée Fleming and Susan Graham.
