Jay-Z helped close out his Made In America music festival tonight by joining Sunday's headliners Pearl Jam for a rendition of "99 Problems." It was quite a moment for those in attendance, and word quickly spread through the Twittersphere of the onstage collaboration between two of the greatest American music acts of all time. Watch above as Hov makes history alongside Eddie Vedder and Pearl Jam with a monumental performance of his Rick Rubin-produced hit song. Wow.
