Pascal provided a handy translation:
Thought up as the direct successor of BiS by the producer Watanabe Junnosuke, BiSH (Brand New Idol SHit) consists of six singers/dancers in the service of particularly dynamic and clever music. Pop melodies over a rock instrumentation and pop-punk energy form a powerful, exciting and inventive result that already won a beautiful (deserved) success in the Japanese charts. “Alternative idols” lovers will be spellbound!

It’s just a small thing, but it’s a step. I want to see them covered in Rolling Stone.
