WATCH: Kendrick Lamar Debuts 'Poetic Justice' Video Featuring Drake

Kendrick Lamar on Friday released his latest music video, this one for the Drake-featuring “Poetic Justice,” which is off his incredible 2012 debut album good kid, m.A.A.d city. The dark, smoky set of visuals appear to be greatly inspired by by the work of director John Singleton (Boyz n the Hood, Poetic Justice) Drake also goes back to his Degrassi roots, albeit briefly, with his featured role. Meanwhile, Lamar's character is half of a heart-rending duo, whose love—in Singleton fashion—is ill-fated.
