Ax adds an almost improvisational fluidity to Brahms’ Second Piano Concerto, a piece that combines harrowing pianism with symphonic muscle. Also, Russian conductor Andrey Boreyko leads the symphony in Zemlinsky’s symphonic fairy tale based on the Hans Christian Andersen tragedy The Little Mermaid. $35–$245, 415-864-6000, sfsymphony.org
