NDuaDuo is a po-po-f(aux)k music group residing in Shizuoka City, Japan. For a definition of "po-po-f(aux)k," the best thing to do is to refer to Chapter 96 of When a Sissy Climbs a Mountain in May, where it's all explained . . . but basically, the members of NDuaDuo go hiking, feel joy, feel inspiration, get to breathing just right, have words appear in their heads--and then they go home and strum a ukulele and try to sing all they thought and felt.
