Death metal band Unfathomable Ruination are to perform in an airtight, soundproofed box outside the Gherkin in London this week.
Visible but inaudible to the public, the band's set will form an art installation by Portuguese artist João Onofre called 'Box Sized DIE', which is part of new exhibition Sculpture in the City.
"The box is soundproofed, determining and restricting the performance’s duration to the length of time in which the oxygen is expended," a blurb on the installation reads.
"Outside the cube, viewers observe its strange vibrations, only viewing the band’s entrance and exit to the performance space."
Packed into the tiny cube, Unfathomable Ruination will play tracks from their album, possibly including hits like 'Edges of Disfigured Atrocity' and 'Futile Colossus Decapitated'.
The band will perform from 3 July - 1 August 2014 at 6pm Wednesday to Friday.
In another exercise of musical futility in the name of modern art, The National last year played their track 'Sorrow' for six hours straight at MoMA, an installation Icelandic artist Ragnar Kjartansson titled 'A Lot of Sorrow'.
