Meet BiS, the new shock
They seem to have been formed when a bored female Jrocker called pour lui got even more bored with the shit she was releasing, and decided to form an idol group. Thus, BiS. At least BiS doesn't have quite as terrible a use of autotune. (Yes, I'm aware not all of Pour Lui's songs were that shit. But hell...)
But yes, just to whet your appetite I'll give you the first BiS PV I'll link to. It features headbanging. It also features high octane lesbianism that would make t.A.t.U proud. More on that later.
