Unheard is a festival that will examine not only the physical properties of sound, but also its command of our psychology: how expressive sound articulations like music can bring us together, how sound supports and manipulates moving image, how sound can both heal and disrupt, and how sound is felt as opposed to heard. The festival will also investigate the historical, social and cultural contexts of sound in our city: how musical styles like Cantopop have evolved with time and technology, and how the urban acoustics of Hong Kong interacts with its citizens’ physical and psychological wellbeing.
