Let's Face the Music and Dance

During the Great Depression, music often served to cheer people up. More recent economic downturns gave us the dark sounds of punk and grunge. Today, we'll look at the correlations between music and the economy with Eric Weisbard, critic and curator at the Experience Music Project. Also: Kayhan Kalhor, an Iranian composer and virtuoso of the kamancheh, the Persian spike-fiddle, has been a member of Yo-Yo Ma's Silk Road Project. He shares his own cross-cultural music, as featured on the new album, "Silent City."
