Alien Weaponry are a thrash metal band which often sings in te reo Māori. This Vice documentary meets them as they prepare to tour Europe, and take the metal world by storm. The quiet lives of the members — Lewis de Jong and Ethan Trembath attend different high schools, while Henry de Jong is an apprentice mechanic — are contrasted with a high intensity performance (at the Auckland release show for the band's debut album Tū). The de Jong parents share stories about their two sons, and the band travel to Lake Rotoiti, to reconnect with their whakapapa.
Alien Weaponry shot to prominence in 2016, after becoming the first band to win both the Smokefree Rockquest and Pacifica Beats contests, with their unique brand of te reo-infused thrash metal. The band's debut single 'Urutaa' followed later that year. Released in 2018, first album Tū was streamed over a million times on Spotify in its first week of release. Signed to Austria's Napalm Records, Alien Weaponry performed at Slovenia’s Metaldays festival, plus one of the world's largest heavy metal fests — Wacken Open Air in Germany — fulfilling drummer Henry de Jong's goal of playing at Wacken before he turned 20.
