With eight stents in his heart, a liver transplant, the loss of every past musical friendship undone by his own ego and abuse, and a lifetime of drug use culminating in a surrender to the FBI and subsequent jail time, David Crosby himself marvels that he’s able to keep recording and going on tour, as is depicted in this exuberant and poignantly human rockumentary produced by Cameron Crowe. What sets Crosby apart from so many aged rockers is the unfaltering quality of his voice, which can be witnessed in the recent concert footage that’s sprinkled in with stunning archival photos, videos, and interviews tracing back through his career with The Byrds and Crosby, Stills, Nash & Young. The heartfelt and brutally honest introspection of Crosby—laying bare the best and worst of his experiences as a countercultural icon—makes this an unforgettably moving rock biography.
