4. Barclays Center, Brooklyn
Jay Z inaugurated his home borough's new arena with a string of triumphant shows last fall, wearing a Brooklyn Nets jersey as he joined the crowd in toasting "a celebration of the place where I'm from." Barclays is the first major sports arena in Brooklyn – and it's quicky become a major draw, attracting acts like the Stones, Paul McCartney, Leonard Cohen, Rihanna, Vampire Weekend, Phoenix and more.
Fun fact: Building the arena cost $1 billion.
