The song: Third Eye
Kellee Maize is from Pittsburgh and you will be hearing a lot more from her I am sure. I caught her live performance at media relations impressaria Jennifer England's first On the Spot benefit fundraiser, and it was all terribly legit and hardcore, notwithstanding the slight Ke$hakira vibe in the above music video.
"Spitting rhymes like a full clip," I believe is what it's called. You can access her other tracks here.
