Last week, French duo Justice released an ambitious video for "Heavy Metal" off their Grammy-nominated album, Woman Worldwide.

The video directed by Filip Nilsson features the acclaimed 220-member Norfolk State University (NSU) Spartan Legion marching band. Under meticulous direction, the video is a stunningly choreographed vision - not just musically, but physically as well.  

Gaspard Augé and Xavier de Rosnay, better known as Justice, have now shared a behind-the-scenes video chronicling the remarkable achievement. Through the video, the sound of the Spartans weaves in and out of the mix with the album version of the track. 

The making-of video details the journey from prepping the huge ensemble for the performance to the subsequent shoot. After tireless rehearsals over five days, the 220-member ensemble came together in perfect harmony resulting in the success of the mammoth video. 

Woman Worldwide is a remix album which features a number of mashups and reworked tracks from the duo's catalogue from over the years. The album as a whole was conceptualized on the basis of how Augé and de Rosnay adapted their classics during live performances. While "Heavy Metal" was originally from their 2016 album Woman, this version is a blend of "Heavy Metal X DVNO."
