Presenting: Invisible Cities
Curated by Fällt designers Fehler, 'Invisible Cities' offers the opportunity to experience an intimate series of portraits of twenty of the world's cities painted with sound.

Twenty artists were invited to contribute a five minute audio work inspired by and utilising the sounds of the cities they cherished. Their contributions range from quiet and contemplative to noisy and frenetic with styles ranging from the pristine digital crackles of Washington DC based artist Richard Chartier to the near-silence of Tokyo based ultra-minimalist *0 (Nosei Sakata). 'Invisible Cities' was commissioned by the Naughton Gallery at Queen_s for Belfast Festival at Queen_s 2002.
