It's kind of funny, it appears to be set up by the guitarist and he's made a big back story (set in the future) about how all music no matter what kind connects people. I don't really know if it's quite as manufactured as BabyMetal but Doug Aldrich had the guy at his NAMM show and one of the girls was slotted as a replacement from one of the BabyMetal girls. They've only got a few songs out by the look of it so it's a bit hard to tell how talented the musos are.
