Though it was written in 1955, Trouble in Mind, Alice Childress’s play about backstage racial tensions on Broadway, feels startlingly—and depressingly—contemporary. The play happens in a red brick rehearsal room where the (mostly black) actors and (white) director/producer simultaneously navigate the silly theater politics of making a new play, plus the much more serious cultural politics of black people deciding whether and how they want to reenact what white people think they’re supposed to do and say onstage. It’s a bumpy ride. (Intiman at Cornish Playhouse at Seattle Center, 201 Mercer St, intiman.org, 8 pm, $20–$50, through Sept 15)
