At 78, Lucinda Childs is about to pivot—again. The postmodern choreographer and director came to prominence in the 1960s and '70s, first with Judson Dance Theater and then with her own eponymous company. She shut down her troupe almost two decades ago to work as a freelance director, relaunched it nine years later to stage a couple of revivals...and then just kept going. We spoke to her as the company was getting ready to wrap up its final season, which included a summer staging of Available Light—a 1983 work developed with John Adams and Frank Gehry—at Lincoln Center's Mostly Mozart Festival, as well as final performances Oct. 29–Nov. 4 at New York City's Museum of Modern Art.
