How does the art of composing reconcile spiritual strivings? What's the creative process of transcribing disparate voices into a unified whole? In what ways does the music of the African Diaspora express cultural unity and the individuality of nations such as South Africa, Brasil, Cuba, or the United States? On Friday, March 21, 2014, we'll trade fours with low-brass specialist, Joseph Daley whose CDs The Seven Deadly Sins and The Seven Heavenly Virtues capture the complexities of the Diaspora and the spiritual strivings contained therein. Join us on Trading Fours -- 11AM Eastern, 8AM Pacific -- and "Get in on the rhythm."
