Hip-hop star Jay-Z joined Pearl Jam on stage for an encore at the end of a two-day festival yesterday with a rocking version of his signature hit "99 Problem", reports SAPA. While Jay-Z closed out the first night of the Budweiser Made in America Festival, he handed the torch to the Seattle-based grunge rockers and they did not disappoint. Their 25-song set saw tens of thousands of fans jumping, dancing, and singing on the muggy September night to band's well-known tracks like "Alive," "Better Man," and "Jeremy." But Pearl Jam wasn't the only big story, as earlier in the day Run DMC performed for the first time in over a decade. Taking the stage under a video banner that read "Jam Master Jay Forever," the Queens, New York, natives were well received by fans who danced to the music and sang along, some better than others.
