The Effect of Gamma Rays on Man-in-the-Moon Marigolds

Ray Tatar unveils his newest stage—a 30-seat yet-to-be-named theater—with a production of a somewhat forgotten play. Though the story of a shy teen science nerd who is dealing with an abusive, alcoholic mother and a sarcastic older sister is damned depressing, in this small venue and a sympathetic cast, it’s a play that really resonates. The sensitive cast includes Deborah Shalhoub as the mom from hell, and two talented young actors, Jackie O’Brien and Carissa Meagher as her abused daughters, all who make you really care about the characters.
California Stage, 8 p.m. Fridays and Saturdays, 2 p.m. Sundays; $12-$20. 1723 25th Street; (916) 451-5822, www.calstage.org. Through July 20.
