Opening night of Green Day’s “American Idiot” at the Mark Taper Forum last week hosted a raucous packed house. Three distinct types of audience members were in evidence: hardcore fans of the 0Æ90s skate-punk band (wearing black shirts and red ties in homage to frontman Billie Joe Armstrong); enthusiastic members of the Deaf community, thrilled at the chance to see this groundbreaking collaboration between Deaf West Theatre and Center Theatre Group; and lifelong devotees of CTG, relishing the highly anticipated reopening of the Taper after a nearly yearlong closure that shocked the theater world and threw CTG’s future into question.
