Most 20-year-olds who attend Duke University have time to do only two things: study and support Blue Devil basketball. Luckily for us, Michigan native Mike Posner is not “most 20-year-olds.” Along with his group, The Brain Trust, Posner is looking to educate the student body on his hip-pop talents, both on the mic and behind the boards. On Smoke n’ Drive, Posner backs his lyrical lesson with soft piano notes and hard-hitting synthesized drums, and provides a gruff chorus encouraging listeners to “roll the windows up, light it up, and take a puff.” Providing feature accompaniment are Great Lake State emcee and G.O.O.D. Music signee Big Sean and Georgia natives Donnis and Jackie Chain. Posner’s DJ Benzi and Don Cannon-presented mixtape, A Matter of Time, is available now for free download; take a listen… and then get back to your homework.
