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.) by Brendan Kiley
