Earlier this year, classic rap weirdo Kool Keith teamed up with Real Bad Man on the collaborative album Serpent. In a couple of weeks, Keith will follow that album with Black Elvis 2, his sequel to his 1999 cult classic. We’ve already posted Keith’s “Black Elvis 2 (Intro),” and now he’s teamed up with underground fixture Marc Live and fellow ’80s titan Ice-T on the new track “The Formula.”
