If you haven’t heard of Baby Metal, you’re about to. No this is not a joke. Not even a little bit. So pay attention. Because maybe we told you first. (Maybe not.)

This teenage trio (age 14-16), dressed in what looks like your little sister’s Hot Topic attire, sings pop music over heavy metal, and has dance moves that ‘match’. Regardless of whether or not you think it’s good, it’s getting popular. The young, dare we say starlets, just got signed to a major recording deal. Their first record came out at the end of February to the tune of 30k copies sold in the first week. And coming up they make their U.K. debut at Sonisphere Festival.

When will the girls land stateside? It’s TBD. But after getting vetted by Megadeath alum Marty Friedman, we’re thinking it won’t be long. What will the American reaction be? Welp.
