A documentary filmed by Adam Small in the early eighties about an american tour featuring punk bands Social Distortion, Youth Brigade and Minor Threat. It featured clips from the 31 concerts that were played, a myriad of interviews (including some from the bands themselves,local kids from the punk scenes of the cities they were playing at, and even a few by ex-Black Flag and Circle Jerks Frontman Keith Morris).
Another State of Mind is a great rock documentary featuring some great bands.
