Ras Kass: "Focus" F. Kendrick Lamar & ProVerb

Having assumed the "New King of the West Coast" title, it's hardly a surprise that some of the state's greats have co-signed Kendrick Lamar. Joining the likes of Snoop Dogg, MC Eiht and, of course, Dr. Dre, veteran Carson, California MC Ras Kass gives the Black Hippy star his nod of approval by welcoming him, along with ProVerb, onto his new track, "Focus."

The nostalgic G-Funk-esque offering can be found on Kass' brand new mixtape, BArmaggedon, which also features appearances from Snoop Dogg, Raekwon, Evidence, The Alchemist and Immortal Technique. Available to download here, the mixtape serves as a prelude to his forthcoming album of the same name, due out Dec. 19.
