Join IPR's Barney Sherman for four hours of classical music this afternoon starting at 1. Along with music of Poulenc, Beethoven, Brahms, Tchaikovsky, and more, Barney will begin a daily series of reconstructions of lost works by J. S. Bach, "Back-engineered Bach." Up today: the Cello Suite no. 4, which may have started life as... well, tune in to hear!
