7 p.m.
Metal, Rock

As the self-proclaimed inventors of “kawaii metal,” Babymetal specialize in aesthetic extremes: pummeling beats, giant whomping blocks of guitar sludge, hyperfeminine pop sugar, exaggerated theatricality, and the confident delight of knowing how batshit your dialectic is. The synthesis works because the riffs are catchy and awesome. The Japanese band’s third album, Metal Galaxy, comes out October 11. With Avatar.
