Beethoven's 'Emperor' Concerto
When Napoleon's army attacked Vienna in 1809, Beethoven took cover in a basement. When he emerged, he found that his piano and the music he'd been working on were still intact. He got right back to it and finished the piece. On today's show, hear a composition that survived Napoleon troops: the Piano Concerto No. 5, widely known as the Emperor Concerto, by Ludwig van Beethoven..
