Usher addresses police brutality on his new Nas-featuring song, “Chains.” The track is accompanied by an interactive video hosted on TIDAL’s website that displays photos of unarmed murder victims, most of whom were killed by the police. The video asks for access to your computer camera before it begins, and stops every time you avert your eyes from the screen. “To listen to Usher’s song ‘Chains,’ look in the eyes of unarmed victims,” the introduction reads. The video and track are available here.
