Adroitly directed by Kevin Heckman, this is a sprightly production of Victoria Stewart’s smart if occasionally self-conscious script. The pornography of performance art takes center stage–but we’re not talking Annie Sprinkle. Stewart is less concerned with the politics of porn than she is with the exploitation inherent in documenting social injustices. Demetria Thomas as the imperious academic/performer and Christine Gatto as the sly sex worker she’s interviewing seduce each other with barbs and personal revelations while the artist’s assistant files it all away. You have to wonder whether Stewart, who once assisted Anna Deavere Smith, is getting payback, and the final twist feels pat, but overall this is a witty portrait of voyeurism disguised as social conscience. –Kerry Reid a Through 6/2: Thu-Sat 8 PM, Sun 3 PM, Stage Left Theatre, 3408 N.
