Like most of you, my initial reaction when hearing BABYMETAL was "What the hell did I just watch?"
The group is really the women singing and dancing in front. The backing band is session musicians - consistent, known ones, but they aren't the focus. The focus is the women that you are expecting to sing light pop music, and who instead blow your expectations out of the water.
The music is metal. It's metal that's a throwback to early 1990's bands that rocked this hard. They got their start in 2010 as a subunit of the Japanese idol group Sakura Gakuin,, but broke away and became so so much bigger than that.
The concept was originally a traditional idol fusion with metal music - but it has evolved into something of a reverent metal tribute. This song, which was something of a worldwide breakthrough for them in 2015, deals with a woman's desire to... well, eat chocolate, along with the pressures of maintaining one's figure. I'm not kidding. Enjoy.
