The band’s clangorous, soulful sound fuses age-old genres called gut and minyo with alt-rock rhythms and a bouncy showmanship reminiscent of the B-52s. They call it “shamanic folk pop.” Perhaps the most galvanizing track on their two albums is “Hee Hee,” a celebration of laughter in which ululations spiral in hypnotic rounds. The yips and yelps build and then, when a rasping zither called the ajaeang hits, all but catch fire.
