The two-week PianoFest at SubCulture, the inviting and intimate basement performance space on Bleecker Street, runs through Sept. 27 and presents artists of wide-ranging styles and approaches to the piano. Classical music fans should be particularly tempted by this brilliant, probing Israeli-born pianist's recital on Tuesday, with works by Bach, Mendelssohn, Franck, Matthias Pintscher and, to conclude, Barber's teeming, rhapsodic Piano Sonata, Op. 26, a work introduced by Vladimir Horowitz. It's first-come first-served seating.
