As part of an art installation by Portuguese artist João Onofre, the UK death metal band Unfathomable Ruination will be playing in an airtight, soundproofed box until they can play in that airtight, soundproofed box no more.
Onofre's box has been on tour in Europe and Japan and in each stop, a local "Death Metal band" is invited to play inside. I guess the assumption is the heaviness of the band will translate into the box vibrating? As for the oxygen depletion... uh, no idea. Maybe Onofre equates death metal with "extreme" culture and thusly he's push some biological/physical boundaries by erecting biological/physical boundaries? This installation is happening in London "outside the Gherkin at 6 pm from 7/3 to 8/1."
