Once a small-ish space in neighboring Rockport, the CMCA opened its sleek, airy Rockland  museum in 2016 to much fanfare, and the architecturally striking building on the old waterfront (its spiky roofline is meant to recall the waves) has been drawing crowds since to its three galleries filled with cutting edge (often sculptural or multimedia) contemporary art. In the courtyard outside, a piece from Maine artist Jonathan Barofsky’s 24-foot Human Structures series (he has similar sculptures permanently installed in San Francisco and Beijing) gives you a pretty good idea what you’re in for: work that’s of the moment, a little abstract, and a little eccentric.
