D.C. emcee Uptown XO, looks like he's dropping videos off his Colour de Grey album on a weekly basis now (not mad). For his latest drop, we get the visuals for track #10, the AB The Pro produced (and featured) "Evolution." Watch XO, AB and some lovely co-stars go in with the Backie T directed vid. Colour de Grey is out now via iTunes - get down if you know what's up.
