The magnificent Mitsuko Uchida, praised for her “probing and magisterial” Schubert (The New York Times), continues her multi-season exploration devoted to the Austrian master. A youthful sonata brimming with melody opens the program, which also features the uncompleted but grandly scaled “Reliquie” Sonata. Her recital culminates with Schubert’s last sonata, a darkly shaded masterpiece in which he contemplates his impending mortality while looking back to Beethoven in a gentle and rollicking Rondo finale.
