Last week, Mr. West joined Rihanna at the Nassau Coliseum stop of her LOUD Tour in New York City for a theatrical performance of their hit single "All of the Lights." Thanks to RiRi's official Youtube page, not only were we given the performance, but also a behind-the-scenes backstage look moments before the show kicked off. Watch the two bring down the house above.
