Contributed by David Carrier / Five smallish early Jo Baer paintings are on display in one white- walled gallery at DIA Beacon in her exhibition there since 2022. The show is both tantalizing and exasperating. In the 1970s, Baer became famous as a minimalist painter. Then she left New York, published a manifesto in 1983 proclaiming “I am no longer an abstract artist,” and changed her style completely.
