The summer performance lineup at the amphitheater on Manhattan's Little Island park will open June 6 with Twyla Tharp’s “How Long Blues.”.

AdGiven all that, it would seem obvious that something like a global pandemic wouldn't force Tharp off course, or keep her on the sofa binge-watching Netflix. Tharp explains it simply: "Part of the adventure for me has always been a physical challenge." In one old clip, TV host Dick Cavett asks Tharp what she does to relax after a long period of work. Tharp didn’t want the film, directed by Steven Cantor and part of the American Masters series, to feel like a biography.
