Ads for David Mamet’s new play proclaim it his “most explosive four-letter word yet.” Mamet has always courted controversy on hot-button issues. “Race”, now on Broadway, is about a diverse team of lawyers defending a white man accused of raping a black woman. Kurt sees the show with Hilton Als, theater critic for The New Yorker magazine, who thinks Mamet might not be pushing our buttons hard enough. Produced by Studio 360’s Jenny Lawton.
