Altar Boyz is an Off-Broadway musical comedy about a fictitious Christian boy band from Ohio. It addresses and satirizes, among other things, the phenomenon of boy bands, the popularity of Christian-themed music and products in contemporary American culture.
The show is presented in real time as a concert, the last concert of their national "Raise the Praise" tour, by the five-member group the Altar Boyz and their band. Four of the group's members, Matthew, Mark, Luke and Juan, are apparently named after the authors of the four canonical Christian Gospels. The fifth member is Abraham, who, the group explains in the show's opening number, is Jewish. The members of the group address the audience directly and refer to the venue and location in which the performance is taking place. The Altar Boyz perform several songs, with choreographed dancing in the style of boy bands, and present several scenes concerning the group and its origins, as well as each member's strengths and demons, as part of the concert.
