Death metal band Unfathomable Ruination will be performing regularly outside the Gherkin in London throughout July and early August – but mercifully for those with sensitive ears, they will be doing so from inside a soundproof boxThe unique performance art piece, Box Sized Die, by Portugese artist João Onofre, is part of the public exhibition Sculpture in the City.Each performance will see the London-based band enter a two-metre square, hermetically-sealed steel cube and play a self-described “intense and brutal” set until their oxygen runs out.Visitors to the piece are invited to observe the resulting vibrations from outside.This will be the first time that Onofre’s work has come to London, having previously visited Paris, Barcelona and Basel, Switzerland.Now in its fourth year, Sculpture in the City is a collaboration between the City of London Corporation, local businesses and the art world to create open-air art exhibitions around the City.
