East Wing of the National Gallery of Art. (Randy Mays)

In the Tower: Barnett Newman will focus on the artist’s breakthrough work from the mid-1940’s when he sought a more abstract artistic mode and began using vertical “zips” in his canvases. It will feature the most ambitious work of his maturity, the 14-piece “Stations of the Cross” series.

In the Tower is the fifth show in the Tower Gallery that focuses on art developments since mid-century, and is part of the “Modern American Genius” celebration on and off the National Mall this summer. Other exhibts include Jasper Johns: Variations on a Theme, running June 2-Sept. 9 at The Phillips Collection and Richard Diebenkorn: The Ocean Park Series, at the Corcoran Gallery of Art June 30-Sept. 23.
