David Crosby formed what he views as rock’s first supergroup: Crosby, Stills and Nash. He's faced many hardships: friends who died young, fractured relationships with band mates, drug addiction, a stint in a Texas state prison, and major health problems. Crosby's story is the focus of a new documentary produced by his longtime friend Cameron Crowe.
