Close your eyes, take a deep breath, and reflect on this: The 10th anniversary of 9/11 is right around the corner. Every generation gets its life-changing event. Pearl Harbor. The JFK assassination. And the attack on the World Trade Center, which still seems more like a nightmare than something that actually could and did happen, altering American lives in so many ways. Nashville playwright Valerie Hart goes at those dark memories with a consciously different approach, offering a work “about art set against one of the largest tragedies of our time.” Her tale, inspired by the real-life Eric Fischl public arts controversy in the immediate aftermath of 9/11, is told to us by fictitious characters who explore policy issues about public art — how it is defined, how much should be spent on it, what is deemed acceptable or good, and how and when tragic events should be acknowledged on public property. There won’t be any overt sensationalism in this Rhubarb Theatre production, but the premise is ripe to evoke some serious reaction from a theater audience — and the timing couldn’t be more salient, as 9/11 memorials will soon be upon a sober public. Trish Crist directs, and the cast includes Phil Brady, Maggie Pitt, Wesley Paine, Clay Hillwig, Chaz Howard and Dan Millard. With a tip of its collective hat to those who serve, the company is offering two-for-one tickets to emergency responders — firefighters, police, EMTs and 911 operators — for any performance of the play.
