Gorillaz are seen playing while fire burns all around them. D-12 run into the scene from a distance.
This clip is short, around a minute long. All of Gorillaz' appearances are cut in from previous videos ("Clint Eastwood", "19-2000", "Tomorrow Comes Today"). This clip appeared on the Gorillaz website around the time the track 911 was released for download. The backing soundtrack is part of the 911 song.
