“I work best going to the same places,” the painter Lois Dodd, now 94, said in 2015. “I change, they change, or the weather changes. I used to think the subject would dry up, and I would have to make a move. But that never happened; it is the reverse.” There is a philosophical truth to that statement, and it goes to the heart of Dodd, who works on New York’s Lower East Side, in Maine, and along the Delaware Water Gap. Her modestly sized paintings are often completed in a day, usually outdoors. Dodd uses bristle brushes, which don’t hold as much paint as softer brushes—“I am stingy with paint,” she has said. Celebrating Dodd’s 20th anniversary with the Alexandre Gallery, this exhibition presents approximately 30 paintings. The vision within their seeming simplicity is akin to the poems of Robert Frost. —L.J.
