Such imperfect awesomeness! Whoever did sound doesn’t know hip-hop and poor Jay-Z got slammed with echo. A serious hat-tip to him, he was able to continue through it and then Alicia Keys opened up her awesomeness and totally saved it while they fixed sound. The only thing better is the player’s faces of awe. Oh yeah, and the entire Bronx crowd knows all the lyrics to the chorus! In NEEWWW YOOOORK!
