This breathtaking chronicle follows an ever-surprising group of modern-day cowboys as they lead an enormous herd of sheep up and then down the slopes of the Beartooth Mountains in Montana on their way to market. Call it an abstract Western or the last round-up. Ilisa Barbash and Lucien Castaing-Taylor spent three summers in Montana documenting the process by which sheep are raised, ranched, sheared, and driven hundreds of miles to graze in high pastures of Sweet Grass County. Sweetgrass is routinely awe-inspiring and often hilarious. The Big Sky Country has never looked more spectacular—or, thanks to the ranchers as well as their animals, sounded more cacophonous—and, after Sweetgrass, it will never look the same. A Cinema Guild release.
