Sculpture in the City: Box sized DIE featuring...

Joao Onofre's art work for 'Sculpture in the City 2014' is a sculpture and a performance. Inside a two-tonne, black steel box - and with the door closed - a Death Metal band, 'Unfathomable Ruination' will perform an invisible show for spectators. Sitting inside the box, Joao talks to Andrew Buckingham from the City of London Corporation, one of the project partners, about how he came up with the idea.
