Mask (Stage)

A musical about a tortured mother who advances her kid by any means necessary: Mask is kinda like Gypsy, but with facial deformities. The 1985 movie, with its malformed teen-boy hero, turns out to be surprisingly rich material for a tuner. But oh, those tunes. The only respite from Barry Mann and Cynthia Weil’s numbingly hyper-inspirational power ballads comes when they’re writing ”kick-ass chrome crusade” anthems for the motorcycle-gang chorus. Shamelessness is redefined when the doomed lad bikes and belts his way into heaven at show’s end. But Michelle Duffy keeps things rocking as the meth-addicted biker mom we all wish we’d had.
