Imagine a world in which classical ballet, modern dance icon Martha Graham, and questions of cultural appropriation collide with clowns, basketball players, and hula dance, and you may begin to grasp the creative force, intelligence, and wit of choreographer Ann Carlson. In “Elizabeth, the Dance,” she pays homage to “the visionaries and teachers” of modern dance history. With movement both formal and physically awkward, deliciously surprising and joyfully restrained, Carlson has created an astonishing tribute to modern dance and to the joy of being human.
