Watch for: Watch the Throne

This is one of hip hop's greatest collaborations since Diddy and Biggie... actually, no... this is bigger than that. Both artists have been independently and explosively successful and now the superstar duo has united to work on 2011's most highly anticipated music project.

In August Kanye West tweeted that he and Jay-Z would release an album together. Now, after the release of "H.A.M.", that is becoming more of a reality.  The album Watch the Throne will be released this summer. Click here for more on their musical history.

SIDENOTE: Kid Cudi, who has been busy working on his video for "Maniac" with director Shia LeBeouf,  working on a rock album Wizard, working on other projects with Kanye and Jay, and filming the second season of "How to Make it in America" on HBO,  will also be releasing an album this summer-- his second official mixtape A Man Named Scott. He is back on Twitter, so follow him for further updates.
