Dominion Stage mounts a production of the off-the-charts Charles Busch camp classic Psycho Beach Party, a mashup of mid-20th century-era beach movies and Hitchcockian suspense thrillers, with a heavy dose of split personalities thrown in for extra delight. Emily Ann Jablonski directs. Opens Friday, June 3, at 8 p.m. Weekends to June 18. Dominion Stage -- Gunston Arts Center, 2700 South Lang St. Arlington. Tickets are $15.
