Here are Baidoku, who could be my new favourite band.
Their incredibly cute bass player starts by rearing a strip of tape over her nipples which she removes at about 2:12
I can't find any other footage of them other than low quality form quite a way away. It seems that she pretty much always ended up the shows topless. Can't find any good still images either
