In "Finding Center," the choreographer David Parsons and the visual artist Rita Blitt demonstrate their shared mastery of swirling, spiraling shapes. That work, appearing one on of the two programs comprising the company's Joyce Theater engagement, is joined by Katarzyna Skarpetowska's "Almah," a work inspired by her childhood in Poland, with accompanied by live, original music from Ljova. Other works from Mr. Parsons, including his famous light trick solo "Caught," round out the two programs, along with "Train" by Robert Battle. Saturday and Sunday matinees are designated "kid-friendly."
