Playwright Robert O’Hara is known for exploring the intersections of class, race, and sexual identity in unexpected ways. His breakout Insurrection: Holding History (1996) used time travel as a device to revisit American slavery; Bootycandy (2014) took a comedic but pointed look at the challenges of being a gay black man. Hilton Als of the New Yorker has already called O’Hara’s new play, Barbecue, “my idea of an American classic, or the kind of classic we need.” There’s no better venue than Mixed Blood Theatre for this rowdy piece to have its local premiere. Barbecue is about a family mounting a questionably conceived intervention at a picnic. They’re not afraid to give offense to each other or to the audience, and O’Hara further complicates things by flipping the script: We see the family in alternate universes, as both white and black. Eventually, the worlds intersect. A stellar cast — including Regina Marie Williams, Stephen Yoakam, Jevetta Steele, and Sue Scott — will bring this darkly humorous tale to life.
