In the most nonchalant way possible, Stones Throw’s Homeboy Sandman has shared a new video for “Bus (A Rhyme),” which finds the rapper heavily promoting mass transportation while writing rhymes on a moving bus.

Produced by Onra and directed by Steven Miosku, “Bus (A Rhyme)” seems like spur of the moment idea, and could quite possibly be just that with its grainy visuals and raw sounding vocals.
