When this satire of boy bands, Christian pop music, and the uneasy mix of faith and commercialism in America opened its national tour last fall at Chicago's LaSalle Bank Theatre, it provided ammunition for the argument that the theater business needs to find some new models for presenting shows of a smaller scale in touring and regional productions. Do shows like Avenue Q, tick, tick ... BOOM! and Altar Boyz belong in one of the 2,000-seat renovated movie palaces or vaudeville houses that host all the national tours these days? Forgive the easy analogy, but, as the Bible says, "ask and ye shall receive," for Chicago has received its own sit-down production of Altar Boyz in the very comfortable and intimate 450-seat Drury Lane Water Tower Place Theatre. In a further deviation from prevailing road and regional practices, it's being presented by a new team of New York producers (Joe McGinnis and Bart Kahn) rather than the impresarios of the original production still running Off-Broadway in New York. Regardless, the production has an imprimatur of authenticity thanks to its being directed by Stafford Arima and choreographed by Christopher Gattelli, both of whom had the same responsibilities for the New York and touring productions.
