WQXR Beethoven 32-Piano Sonata Marathon

As part of WQXR's clever marketing scheme, Beethoven Awareness Month, the composer's glowering visage can be seen all over New York, pressuring you to check out this marathon performance of all 32 of his legendary piano sonatas. Considering the lineup—local keyboard gurus including Inon Barnaton, Alessio Bax, Jonathan Biss, Jeremy Denk, Benjamin Hochman and Joyce Yang—we'd stop in even if we didn't feel strangely threatened. The complete schedule is available at thegreenespace.org.
