The artist Keane has also been involved in this project during the 2009 and 2010. He has been listening to the music that Andrea has been producing right from the start of this project and has been producing images based on what he could hear. Leaving aside his normal medium of canvas and paints, he has been producing a series of black and white monoprints.
The book Invisible Cities by Italo Calvino explores imagination and the imaginable through the descriptions of cities by an explorer, Marco Polo. It is framed as a conversation between the aging and busy emperor Kublai Khan, who constantly has merchants coming to describe the state of his expanding and vast empire, and Polo. The majority of the book consists of brief prose poems describing 55 cities, apparently narrated by Polo. Short dialogues between the two characters are interspersed every five to ten cities and are used to discuss various ideas presented by the cities on a wide range of topics including linguistics and human nature.
