Little Blue Ivy Carter is sure to be at the Barclays Center in Brooklyn on its September 28^th opening night.  That is because her daddy, none other than JAY-Z himself, will be performing to a sold-out audience.  We have two tickets for you to hear this 13-time Grammy Award-winner live.  And, keep your eyes peeled, because we’re also getting you a backstage tour, so you may just catch a glimpse of a (no longer) Single Lady named Beyonce.  Sounds like a good night, right?  Right.  So make it rain for Playwrights Horizons now, okay?
