Rapper Jay-Z hosted the Budweiser Made in America Festival in Philadelphia, but not surprisingly, he didn't stay on the sidelines.
At the end of closing act Pearl Jam's set, Hova joined the band for a rendition of "99 Problems," capping a successful show for the long-standing grunge rockers. The band rolled out several politically-charged covers, including the Clash and Ramones hits, and original staples of its live show.
The festival also featured a reunion of Run-DMC members Rev Run and D.M.C., as well as shows by The Hives, Drake and Odd Future Wolf Gang Kill Them All.
