“Dust My Broom,” the 1936 blues classic by Mississippi-born Robert Johnson, is just one example of artistry that brought African-American culture out of the shadows. Since then, arts traditions in the southern vernacular—including but not limited to assemblages, sculptures, and paintings made of found or repurposed objects—have become mainstream. They now constitute a distinctive legacy. This exhibition is the largest-ever at CAAM dedicated to art developed in the American South. —E.C.
