[Aired on Wednesday, February 29th.] (Note: This show originally aired last year.) Today we speak with the music historian, writer, and educator Harvey Sachs, whose latest book, just out in paperback from Random House, is "The Ninth: Beethoven and the World in 1824." It's a fascinating, in-depth, and wonderfully readable account of the creation and reception of one of the world's immortal pieces of music: Beethoven's Ninth Symphony.
