Episode No. 594 features curators Stephanie Mayer Heydt and Isabel Casso.

With Audrey Lewis, Heydt is the co-curator of "Joseph Stella: Visionary Nature," a survey of the American modernist's nature-based artworks at Atlanta's High Museum of Art. While Stella is best known today for his futurism-informed studies of urbanity, most especially for his paintings of the Brooklyn Bridge, Lewis and Heydt's exhibition reveals him to be every bit as much as interested in re-making America's century-long Emersonian landscape and nature traditions as his Precisionist colleagues were. The exhibition features over 100 paintings and works on paper. It's on view through May 21. A fine catalogue was published by the High Museum of Art and DelMonico Books. Amazon and Indiebound offer it for about $55.

With Kate Green, Casso is the curator of "Celia Álvarez Muñoz: Breaking the Binding," the artist's first retrospective, at the Museum of Contemporary Art San Diego. The exhibition features over 40 of Muñoz's large-scale installations, book projects, and shows how Muñoz built a witty, often funny style built from conceptualist puns even as she styled herself as an "artivist" who engaged issues informed by her experiences living along the US-Mexico borderlands. It's on view at MCASD's La Jolla location through August 13. A catalogue is forthcoming.
