Defiantly riffing on the rigorous abstractions of the fifties and sixties, New York–based painter Mary Heilmann cuts through the genre's occasional academicism with lush colors and a woozily applied impasto that suggest she's having a great, groovy time. In paintings like Neo Noir, hung in her current retrospective at the New Museum, Heilmann evokes both messy life and high art — it's like how Mondrian would have seen the city on a jittery walk home from a jazz club (after a toke too many). "Mary Heilmann: To Be Someone" is on view through January 26.
