I don't know quite what to make of it....
Eh, doubt it. These girls were just run of the mill j-pop singers before this. Apparently some Japanese label picked them up and created this oddball image for them. The girls weren't even familiar with metal before the group began. Female group J-pop is a pretty tired genre at this point, believe it or not. I think at some point, a metal version of such a group was inevitable. The female signer trio is done to death over there.We'll be seeing them on Celebrity Rehab in about fifteen years.
