Joan Mitchell: Paintings from the Middle of the Last Century, 1953 – 1962 is a fine exhibition of works of one of  America’s leading Abstract Expressionist painters. Notoriously difficult and prickly, Mitchell nevertheless distilled poetry, nature, and music into daring compositions of boundless energy. In this Untitled work from 1958 bold horizontal brushstrokes interplay with patches of light and dark to expose figure and ground and scarlet red joins with forest green and marigold into a blustery autumnal outing… This marks the last exhibition for Cheim & Read of Mitchell’s work. The eminent gallery lost the estate of the artist to David Zwirner. It is preceding a major retrospective of the artist in 2020 at the Baltimore Museum of Art which will travel to the SFMA and the Guggenheim Museum and which will surely unleash an unbridled market frenzy that Mitchell would have thoroughly disdained. At Cheim & Read through November 3.
