During last night's final game of the NBA season at the United Center in Chicago, Ill. between the hometown Bulls and the Detroit Pistons, a fan gave an amazing air guitar performance rocking out to Power Trip's "Executioner's Tax (Swing of the Axe)."

The Bulls used the devastating Power Trip cut for their "Air Guitar Cam," during a break in the action. A seeming mild-mannered fan singled out and shown on the arena's video screens. He hesitates, then stands up and rips off his long sleeve button down shirt to reveal an Anthrax shirt. The crowd roars as the man delivers an air guitar performance for the ages.

Power Trip took to Twitter to post the clip with the caption, "No escaping the power of the riff." While the clip could be staged, it is a great moment for sure and one that requires multiple views. Watch it over and over below.

The band's track “Executioner’s Tax (Swing of the Axe)” won Metal Song of the Year at the 2017 Loudwire Music Awards.

Power Trip will head back out on the road on April 27 in Jacksonville, Fla. See all their tour dates here.
