BiS @ Tokyo Ryogoku Kokugikan

After the 'naked' promotional videos, the guillotines and the death threats, confrontational idol group BiS might finally have reached the point where they're more famous than the '90s Scottish indie trio whose name they stole. But would you pay ¥50,000 to see them? That's how much the 'premium' tickets cost for this gig at Tokyo's sumo stronghold, though fans (and you've got to be a member of the fan club to qualify) will also get to take part in a meet-and-greet, and go home with a pair of signed T-shirts and commemorative photo. If you'd rather watch from the comfort of a cheaper seat, you can do that too – in one of the small two-person boxes usually reserved for sumo audiences.
