On April 1, a.k.a. Fox Day, Japanese pop metal act BABYMETAL released a cryptic video to mark the start of "Metal Resistance Episode VII".
According to the clip, "a new era is about to begin," with a voiceover saying: "Light and darkness. Both are considered to be opposites but at the same time, one cannot exist without the other. Until now, we have only experienced the light side — the legend of three metal spirits. An unknown dark side also exists. A legend of seven metal spirits — The Chosen Seven. A new era is about to begin."
BABYMETAL has also announced the release of its two concerts from December 2-3, 2007 at Hiroshima's Green Arena on a new Blu-ray titled "Legend S - Baptism XX". The limited-edition set, featuring 16 songs, a live CD and a booklet, will only be available for members of the band's fan club, The One.
BABYMETAL played the Hiroshima concerts without one of its three female singers. Yui Mizuno (a.k.a. Yuimetal) did not feel well and doctors suggested that it was in her best interest to not join her bandmates on stage.
Established in 2010, BABYMETAL is the offshoot of the Japanese pop idol group SAKURA GAKUIN that performs a distinctly Japanese mix of schoolgirl J-pop and heavy metal.
BABYMETAL's members — Suzuka Nakamoto (a.k.a. Su-Metal, who handles vocals and dancing), Mizuno and Moa Kikuchi (a.k.a. Moametal), the latter of whom both scream and dance — admit that they had never listened to metal before joining the group. The girls wear gothy schoolgirl costumes, do choreographed dance routines and bang their heads violently.
