Before he made his leap to stardom as the musical director of The Late Show with Stephen Colbert , Jon Batiste already showed signs that he wanted to change the world for the better. Batiste, 32, will headline a special concert at the Newport Jazz Festival next Friday, at the International Tennis Hall of Fame. He has a new album releasing on the same day: Anatomy of Angels: Live at the Village Vanguard (Verve), which was recorded during an engagement last fall.
