Is George Gershwin's masterpiece an opera, as he labeled it, or a sung-through musical? Is its story a patronizingly paternalistic portrait of African Americans in 1925 Charleston, South Carolina, or an historic advance, for its time, in depicting this group as more than servile caricatures? Chicago's Court Theatre—whose specialties include both downsized re-imaginings of American musical classics and highly regarded productions of African-American-themed plays—is a most logical company to tackle these questions. They've done so boldly, with a conceptual approach that may not be acceptable to the strictest of Gershwin purists, but should satisfy most lovers of this piece and add to their understanding of it.
