Besides all the action that took place at Philly’s 4th of July Jam, DJ Jazzy Jeff literally had a camera man (? woman? team?) with him to capture an inside glimpse of the festival. Watch Jazzy rehearse with The Roots, bring the roof down with his PSK-set, kick it backstage and of course hold down the 1′s and 2′s for everyone from Queen Latifah to Common to the Legendary.
