 Support for BBC World Service on WSHU Public Radio comes from the generous support of the Iqbal and Shelby Mamdani Foundation. Remember, you're going to have the best seat in the house when you tune in for Carnegie Hall Live tomorrow at 3 p.m. on WSHU. This weekend's concert features music for piano, including works by Mendelssohn, Mozart, and Beethoven, and a rousing encore by pianist Daniil Trifonov.
