Rock of Ages is a jukebox musical built around classic rock songs from the 1980s, especially from the famous glam metal bands of that decade. The musical features songs from Styx, Journey, Bon Jovi, Pat Benatar, Twisted Sister, Steve Perry, Poison and Europe, among other well-known rock bands. During the show, 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 musical. Despite the musical's title, the Def Leppard song of the same name is not included in the musical. The original Broadway production ran for 2,328 performances, closing on January 18, 2015 tied as the 32nd-longest running show in Broadway history. Since debuting in 2009, it has spawned replica productions in Japan, Australia and the United Kingdom, as well as several touring productions.
