Last night a special hip-hop moment happened. One of the very best to ever pick up a mic, Nas appeared on stage With Run The Jewels -- one of the hottest up-and-coming duos in hip-hop right **w. Run The Jewels were scheduled to perform as the headliner at 50 Kent, the main outdoor venue at the **rthside Festival in Brooklyn, and they had a very special trick up their sleeves. The Illmatic rapper showed up as a surprise guest to perform his 'God's Son' track "Made You Look" at the end of RTJ's set and your author was on hand to capture the action on video.
