Our 51st season begins with a thrilling program that spotlights the genius of three masters. Ligeti’senchanting Six Bagatelles is a playful excursion through the wide range of delights only a wind quintet can offer, and Beethoven’s landmark Sonata for Cello and Piano, Op. 69, revels in the virtuosic demands placed on both the piano and cello, played here by Zoltán Fejérvári and, in his Festival debut, Narek Hakhnazaryan, whose performances the San Francisco Chronicle hailed as “nothing short of magnificent.” The program comes to a spectacular close with Mendelssohn’s superlative D Minor Piano Trio, which Schumann called “the master trio of our time.”
