Rock of Ages is a rock/jukebox musical, with a book by Chris D’Arienzo, built around classic rock hits from the 1980s, especially from the famous glam metal bands of the decade. The musical features songs from Styx, Journey, Bon Jovi, Pat Benatar, Twisted Sister, Steve Perry, Poison and Asia, among other well-known rock bands. It is directed by Kristin Hanggi and choreographed by Kelly Devine. The show is noted for being more lighthearted and comedic than other shows on Broadway. During performance, the performers frequently break the “fourth wall“, directly addressing the audience and seemingly forgetting (or perhaps reminding the audience) that they are actors in a play.
