Karen Sherman, iconic performer and one of the most inventive makers of choreographic language in the U.S., is also a visual artist. Gosh. Who knew? She’s making her debut with this exhibition, “Minor Bodies.” There are some spiky sculptures resembling pine cones and cat-o-nine-tails, but with surfaces honed to a silky smoothness. Also on view are objects and drawings exploring such diverse epistemologies as the nature of animal sentience, astronomy, and the body. The show is part of a three-part project, titled Universal Donor, that continues next year with a dance-based work.
