The audience sits in the Olympic Sculpture Park, wearing headphones, listening to two invisible men talk out a small drama somewhere in the landscape. The men are best friends and social outcasts, played by two Australian actors with real-life intellectual disabilities. They are also drug dealers—one of them is trying to arrange a score with two arrogant, rich executives while the other sinks into an emotional crisis that threatens to ruin the deal. Watching one humble man's honesty frustrate the rich and contemptuous feels quietly, oddly triumphant. Presented by On the Boards. (Olympic Sculpture Park, 2901 Western Ave, www.ontheboards.org. 4 and 7 pm, $24. May 29–June 1.)

The Wilders play hard country, from old-time string-band tunes and barroom honky tonk to raucous gospel, with a good mix of originals and covers (Roy Acuff, Hank Williams, Roger Miller, et al.). And they live up to their name: Their shows are super- energetic and rowdy, with rollicking banjo, fiddle, guitar, stand-up bass, and, best of all, Dobro. There will be plenty of dancing by the band and the crowd; you'll leave this show euphoric, exhausted, and possibly covered in beer. (Tractor Tavern, 5213 Ballard Ave NW, 789-3599. 9 pm, $12 adv/$15 DOS, 21+.)
