My guest is Michael Franti, the musician, poet, human rights activist, and filmmaker. He's the leader of the band Spearhead, and now he's made a film called "I Know I'm Not Alone," about his travels to Iraq, Israel, and the Occupied Territories. In my interview with him, we talk about his experience making that film, and he sings a new, unrecorded song, "See You in the Light."
