The screaming starts when a bespangled Neil Patrick Harris parachutes onstage in 'Hedwig and the Angry Inch' and doesn't stop until he's back in his dressing room. That's the kind of rock-star performance he gives in this spectacular revival -- helmed with fabulous flash by Michael Mayer -- of the 1998 musical (and later movie) by John Cameron Mitchell (book) and Stephen Trask (music & lyrics). Harris' Hedwig is an imperfectly transformed transvestite who grew up in East Berlin before the wall came down, resplendent in the punk drag of a nihilistic rocker but still concealing a heap of hurt under her wig.
