Death metal band will play in airtight, soundproof box until they run out of oxygen

LONDON, July 1 (UPI) -- As part of an art installation by artist João Onofre called "Box Sized DIE," death metal band Unfathomable Ruination will perform in an airtight, soundproof box until their oxygen supply runs out.

The performances take place later this week and in early August outside the Gherkin in London.

The sets by the band, who describe themselves as playing "an intense and brutal style" of death metal, will be inaudible to the audience.

"The box is soundproofed, determining and restricting the performance's duration to the length of time in which the oxygen is expended," according to a description about the special box. "Outside the cube, viewers observe its strange vibrations, only viewing the band's entrance and exit to the performance space."

Onofre has brought the soundproof steel box to other locations in Europe in the past.

"Well since this is going pretty viral already, we shall see you this Wednesday at 8:45am then Thursday and Friday at 6pm," the band wrote on Facebook. "PS- According to the medical professionals who read the Independent, we're all going to die... Challenge Accepted."
