Episode No. 646 features curators Edouard Kopp and Shelley Langdale.

With Kim Conaty, Kopp is the co-curator of "Ruth Asawa: Through Line," a survey of Asawa's lifelong drawing practice. (Kirsten Marples and Scout Hutchinson assisted Kopp and Conaty.) The exhibition, which is at Houston's Menil Collection through July 21, presents drawings, collages, watercolors, sketchbooks, paper-folds and other work. The show is accompanied by an excellent catalogue published by the Menil and the Whitney Museum of American Art, New York. Amazon and Bookshop offer it for $36-$46. 

Langdale is the curator of "The Anxious Eye: German Expressionism and Its Legacy," an exhibition of German expressionist works on paper from the rich collection of the National Gallery of Art, Washington. The show features a wide range of rarely exhibited (and little-known) drawings, as well as prints. It is on view through May 27.
