If anyone was going to get 6000 Danish metalheads to do a haka, it was definitely Kiwi thrash teens Alien Weaponry, who were greeted by this site when playing at Copenhell metal festival in Copenhagen this weekend.

In a Facebook post, festival organiser Morten Skovgaard said he reached out to haka instructor Kane Harnett-Mutu to teach the crowd before they came on stage to do the haka they open their shows with. “I was expecting that maybe 500-600 people would show up for the event,” he wrote. “We ended up with 5-6,000! The sight and sound of that coordinated greeting to the band on stage was incredibly moving (I saw more than one pair of misty eyes up there) and resonated deeply with everyone present.

Alien Weaponry seemed just as surprised as Skovgaard, praising the turnout from “you crazy Danish MFs“.

The band is from the tiny town of Waipu in New Zealand’s Northland region, and sing several of their songs in te reo.
