One of the best documentaries on dance is this one. Released in 2000, it sets the creation of a new dance—Piazzolla Caldera—within the context of daily life in the Paul Taylor company. It’s one of the most intimate, insightful, and moving portraits ever of an artist’s life, the company he keeps, and the sacrifices that art demands. It’s now available for free on the company website, along with other offerings, including a short, rare documentary from 1968. —L.J.
