One of the most explosive worldwide phenomenons in modern music is Babymetal. Unorthodox to say the least, the group’s combination of J-pop “idol” music and heavy metal has sparked the imagination of millions and recruited one of the most devoted fan bases ever assembled.

Babymetal’s roots go back to the Japanese girl group Sakura Gakuin and its popular TV show. Su-metal, Moametal and Yuimetal were all a part of the program, hoping to find success in the pop world. We picked out some footage from the show along with video of Babymetal at its infancy, recording and practicing choreography for “Doki Doki Morning.”

We’ve gotten the opportunity to interview Babymetal a couple of times and it’s always been a joy. We asked them about the fabled Fox God, a lyric in “Awadama Fever” where the girls sing about a “mint-flavored time machine” and we even asked if they listen to any metal music in their spare time.

Babymetal has become an incredible live act, stunning audiences around the world at festivals. We threw in some European live footage of the girls performing “Karate” to tens of thousands of moshing lunatics. The girls also just played their biggest shows to date, two gigs at the 55,000-seat Tokyo Dome.
