Taking to his Soundcloud page, 88-Keys liberated a remix he had started a while back of Talib Kweli's "Upper Echelon" off his Prisoner of Conscious LP. While it's not quite an "official" pairing, I'm still counting it because it's dope! Take a listen to the "Top Tier" remix--which also features Kentucky rhymesayer Nemo Achida!!! They have an unmatched chemistry!!! Peep the stream up top!!
