Episode No. 340 features author Daniel E. Sutherland and artist Otobong Nkanga.

With Georgia Toutziari, Sutherland is the co-author of "Whistler's Mother: Portrait of an Extraordinary Life." The book, a biography of Anna Whistler, explains both the austere woman in James Abbott McNeill Whistler's famed 1871 painting, and Anna Whistler's involvement in her son's career.

Otobong Nkanga discusses her work on the occasion of "Otobong Nkanga: To Dig a Hole That Collapses Again" at the MCA Chicago.
