Compton, California Rap star Game is actively working on his fourth official album, R.E.D., planned for release on Aftermath/Interscope Records. After reconnecting with Cool & Dre for leaked single “Shake,” as well as DJ Toomp, and the album’s executive producers Dr. Dre and Pharrell Williams, Game has finally locked in a session with DJ Premier.

While other star rappers such as Jay-Z, Nas, 50 Cent and Kanye West have all previously worked with the Gang Starr producer, this will be Game’s first collaboration. Yesterday, Game revealed that not only will the song feature a pillar of east coast Hip Hop’s sound, but it will also feature some vocals, in the form of Brooklyn, New York’s AZ.

Previously, AZ has worked with DJ Premier on his own works, 2005’s A.W.O.L. and 2006’s The Format, both released through Koch’s Fastlife imprint. Game has worked with longtime AZ collaborator and Firm band-mate Nas on his last two releases, 2008’s L.A.X. and 2006’s The Doctor’s Advocate.

AZ is presently at work on a 15th anniversary edition of his debut, Doe or Die, due to release next month.

The song has yet to be titled, but HipHopDX will keep you updated.
