Little known fact: Before there was High School Musical, there were high-school musicals. And plays. And monologues. And other theatrics. CSUS’s Lenaea Festival has been hip to this, and has duly celebrated such rituals, for more than half a century. Begun in 1956, Lenaea is America’s longest-running high-school theater festival, annually convening more than 60 West Coast high schools—more than 1,200 students, plus some teachers—for three days of wild thespiantics. Because what is human adolescence if not the occasional highly concentrated weekend full of comedy and drama? Remember, as a certain movie-musical’s finale says, “We’re all in this together.” Shasta Hall at CSUS, 6000 J Street, February 2-4. Showtimes are 10 a.m. to 8 p.m. on Friday, 8:30 a.m. to 10 p.m. on Saturday, and 8:30 a.m. to 9 p.m. on Sunday. Tickets cost $5 per day or $10 for a weekend pass.
