Celebrate the Grateful Dead’s 60th Anniversary with this newly remastered concert doc, capturing the legendary band’s five-night run at San Francisco’s Winterland Ballroom in October of 1974, believed at the time to be their final set of shows. In addition to stellar live footage, mind-bending animation, and interviews with the band and crew, this program features the exclusive theatrical premiere of “China Cat Sunflower > I Know You Rider”, a bonus live performance not included in the film’s original release.
