Crowded into a performing space smaller than many living rooms, John Mossman’s pressure-cooker production is well suited to John Guare’s eccentric, overheated drama about a Maine housewife turned Times Square porn star accused of killing her son. Filled with intense performances and executed at a pace that unifies Guare’s intentionally jagged storytelling, this staging reveals the pockets of brilliance in his sometimes inspired, sometimes just self-indulgent 1977 play. Mossman’s pitch-perfect cast easily negotiates the story’s many mood shifts–from dark to light, grotesque to silly, nihilistic to mildly sentimental. Michele Graff as the housewife is adept at managing Guare’s neck-snapping emotional changes, though she’s especially good at his darkly funny existential soliloquies. –Jack Helbig a Through 3/18: Thu 7:30 PM, Fri-Sat 8 PM, Sun 5 PM, Artistic Home, 1420 W.
