The unexploded bombs symbolize those places and situations that the sounds evoke. They may symbolize political conflicts – in this case we hear the sound of street demonstrations; they may stand for the time bombs of consumer societies – then we hear someone going through TV channels; or they may represent issues in private life and partnership – then we hear someone doing the dishes without saying a word, and the tension in the air is almost palpable. We hear all these sounds and see this unexploded bomb. The question is only when it will explode.
