Alex Terrible (vocalist of Slaughter to Prevail) confirms collaboration with Babymetal.
Deepl translation:
I'm really looking forward to my fight on the 25th of January. I'm looking forward to it. Honestly, I'm tired of training. Fatigue has accumulated a lot. And at the end of February we're going to Australia to play with Slipknot. Then we're going to Japan to shoot a music video with baby metal. And also our music video for the new song is being prepared.
