14/48 is the hit-and-run theater festival that's all about the numbers: In the span of 48 hours, seven playwrights, seven directors, seven designers, seven musicians, and 35 actors will conceive, write, design, score, rehearse, and perform 14 plays. Tonight kicks off weekend number two, and fans of rollicking pressure-cooker theater—where "the experience" is as valuable as the art—shouldn't miss it. (Capitol Hill Arts Center, 1621 12th Ave, 1-800-838-3006. 7:30 and 10 pm, $15, all ages.)
