Philadelphia native 2key has impressed with a series of recent freestyles over popular contemporary beats like Young M.A's "Ooouuu" and ScHoolboy Q's "THat Part," but his rapid-fire, lyrical style finds its most natural home over gritty beats like Nas' 1999 L.E.S.-produced "Nastradamus."

Channeling Nas' hard-edged flow, 2key raps, "No, I'm not Nasty Nas, but I'm still filthy with it" as he delivers a series of relentless bars—kicked off with a tongue-twisting line about barricading himself in a cage with a barracuda.
