This seems to be the week of bonkers girl group releases. From NMIXX to Billlie to CRAXY, these groups are serious about their worldbuilding and intricate concepts. But so far, the music hasn’t always followed suit.
I was surprised when I first heard because it is debut song for JYP but they might have did like that because it is a promoting song for cola cola and Nike's as well. I really like the visuals, dance, and vocals. Its just a little confusing how they transitions the song part.
The thing that was heard before the armies then meet at the climax of so called the battle on ice in Alexander Nevsky would be a. a chorus singing a homophonic phrase. Hope this is the right answer and would be of help.
