Having gone from grade school music teacher to jingle composer to touring background vocalist, her debut album broke big in the mid-'90s--and through a quarter-century of rock/country fusion hits, personal controversies, and health challenges, Sheryl Crow has proven herself a true survivor. This revelatory portrait from filmmaker Amy Scott ("Hal") offers unprecedented access to the artist herself, as well as perspectives from friends like Keith Richards, Laura Dern, Joe Walsh, Emmylou Harris, more. 94 min. Widescreen; Soundtrack: English.
