Band to play in an airtight, soundproof box until they run out of oxygen

A British band is squeezing into an airtight, soundproof box where it will perform until the oxygen runs out.

Death metal group Unfathomable Ruination give their first performance outside The Gherkin in the City of London at 6pm tonight.

But no one will hear it. The only hint of a performance from the outside will be some strange vibrations from the cube.

The band will emerge when they can't physically continue because they have run out of oxygen, and carrying on beyond that could prove lethal.

The performance is part of the City of London's 'Sculpture in the City' exhibition. The cube is an art installation by Portuguese artist João Onofre called 'Box Sized DIE'. According to organisers:

This is the first time that João Onofre’s work, Box sized DIE featuring Unfathomable Ruination has come to London, having toured extensively through Europe at venues including Palais de Tokyo and MACBA.Influenced by Tony Smith’s pioneering minimalist sculpture Die (1962), the steel box serves as a mobile location for performance.

In each location the sculpture travels to, Onofre invites a local Death Metal band toplay, on this occasion Unfathomable Ruination. The box is soundproofed, determining and restricting the performance’s duration to the length of time in which the oxygen is expended.

Outside the cube, viewers observe its strange vibrations, only viewing the band’s entrance and exit to the performance space.
