The formidable Yefim Bronfman presents two Beethoven sonatas, the joyous and inventive No. 11 and the tempestuous Appassionata. Also featured is Chopin’s Sonata in B Minor, a late masterpiece spanning the gently unspooling melodies of its first movement to the relentless surge of its volcanic finale. Galina Ustvolskaya’s highly evocative Sonata No. 4, a work characterized by stark contrasts that reveal a world of ascetic spirituality, completes the program.
