Green Day's "American Idiot" Musical:
Meet the Show's Rocker Cast

In less than a month, Green Day's 2004 punk opus American Idiot will come to life onstage as a bona fide musical at California's Berkeley Repertory Theatre. Idiot's creative team includes Michael Mayer, the Tony award-winning director of Spring Awakening (music by Duncan Sheik), and Tom Kitt, the Tony award-winning composer of this year's rock musical Next to Normal. The show's cast features several Spring Awakening alums as well as former and present cast members of Rent, Hair and the Queen-based musical We Will Rock You — along with a few performers with solo music careers.

Check out the actors' resumes and samples of their performances — and read how Mayer and Billie Joe Armstrong bonded to create this production — as Rolling Stone goes behind Green Day's ambitious stage show.
