Tyler, The Creator and Drake both released the mixtapes that really started their careers (Bastard and Room For Improvement, respectively) in 2009. It’s funny how the one who samples without permission and got a nightclub shut down due to his drug use has a relatively clean public image, whereas the one who’s straight-edge gets constantly criticized for offensive lyrics. I guess everyone’s now blaming the art instead of the person. Pontiac Sunburst for your time (you’ll probably want to google this one).
