On September 27, Azerbaijan launched an attack on the disputed border region of Nagorno-Karabakh and rekindled a decade old conflict with Armenia. Azerbaijan launched artillery, air strikes, and deployed tanks and troops. It also dropped a music video.

The video shows soldiers performing with a wall of tanks and helicopters behind them. Footage of soldiers in dress uniform, tanks firing, helicopters deploying troops, and artillery barrages interspersed the performance. The song—"Atəş" or “Fire”—unfortunately, slaps. It’s catchy and the bass guitar reverberates through the footage, putting the viewer in a nationalist mood. Which is the point.
