ETC Group will present a sound performance that makes use of the space and acoustics of the former bunker that houses MWW. The performance will unfold across different levels and spaces within the building. Its concept was developed in response to the building’s unique characteristics, drawing on the specific properties of its architecture and the way different types of electronic signals behave within it.
