"This album is the most incredible album of my career," Game said to MTV News from the set of his "Pot of Gold" video shoot last week. "First, I'm back with Dr. Dre, which is a bonus and dope for me. Second, executive-produced by Pharrell, co-executive-produced by myself and Mars."
There is also production from Cool & Dre, Hit-Boy, Maestro and Lex Luger and features ranging from Nelly Furtado to Lil Wayne to Busta Rhymes. "And Dre's rapping on the album," Game revealed.
Dre, who oversaw Game's debut, The Documentary, has played a limited role in the rapper's career since Game's fallout with 50 Cent, who is also signed to Dre's Aftermath imprint. Since then, the West Coast production icon hasn't lent beats or his vocals to any of Game's subsequent albums.
In 2009, studio pictures of Dr. Dre, Game and Snoop surfaced, proving that the two were back to work in some capacity. Game wouldn't confirm whether Dre provided a full verse or a hook. When asked, he just blurted out the album's release date: "August 29."
