In Denis Kozhukhin’s solo recital, it is not only Jörg Widmann’s eponymous “Schubert Reminiscences” of 2009 that oscillate between the idyll and the abyss: the Russian pianist’s entire program, his first at the Pierre Boulez Saal in several years, mixes the heavenly with the demonic—from Schubert’s late G-major Sonata and its dreamlike main theme to Ligeti’s “The Devil’s Staircase” étude, to Liszt’s Sonata in B minor, which rises from ominous depths to glorious transfiguration.
