From the press release of the book launch:
When communication fails and silence takes place, new voices emerge. Within an artwork, many voices begin to exist, sometimes they are real, sometimes fictional. Mostly, they depart from an authentic voice. A dialogue in an artwork is itself the making of two yet unvoiced characters. These characters gradually begin to exist as the dialogue unfolds. It is the other, a lover, a friend, an artist or a writer, that unleashes other voices even if they do not exist outside of a text or a book. Understanding friendship and its manifestations is important in order to understand the intertwining of individualities happening in dialogues.
From silence a new order will emerge, new dialogues, new relationships, a new love, new artworks, new texts and new voices.
