According to The Source mag, Jay-Z and Kanye West's highly anticipated new album will hit shelves on the 4th of July:
"The Source has received a solid date for the release of Jay-Z and Kanye West's collaborative and highly anticipated album Watch The Throne: July 4th. The information was shared exclusively to The Source by a source very close to the Hov and Ye super project.
Later on this evening there will be a G.O.O.D. Music event presented by Heineken and Kanye West held at a still undisclosed location in New York City. Rumors are speculating that at said event, Kanye and Jay-Z might be making an announcement about the July 4th release date."
