Hélène Grimaud at Chicago Symphony Center

Prodigious pianist Hélène Grimaud, whose “performances attempt, whenever possible, to shake up conventional pianistic wisdom” (The New Yorker), climbs four summits of the piano literature. Beethoven’s Sonata Op. 109, a work of volatility and ravishing poetry, paves the way for Brahms’ heart-warming Fantasies and his wistfully nostalgic Three Intermezzos, as well as Busoni’s colossal arrangement of Bach’s solo-violin Chaconne.
