With music by Duncan Sheik (best remembered for his 1996 single “Barely Breathing”), this provocative musical combines a sexy book with even sexier, alt-rock based songs like “The Bitch of Living,” “Touch Me,” and “Totally Fucked.” Unlike a lot of musical theater, this isn’t a safe bet for a first date or a matinee with mom. The story follows a group of Teutonic teens frustrated by their 19th-century village’s refusal to acknowledge S-E-X. Left to their own devices, they explore masturbation and sexual fantasies, but shit gets real, fast, and sadomasochism, an act of ambiguous consent, and physical and sexual abuse all occur before intermission. The second act grows darker still. The powerful message and the rollicking soundtrack propelled Spring Awakening to a 2007 Tony Award sweep. $10-$25, 8pm Fri-Sat, 2:30 Sun, The Playhouse, 800 W Ashby, (210) 733-7258, theplayhousesa.org.
