It's one thing to write a text, but another to read it out loud and in front of an audience, where one becomes vulnerable. On the other hand, through this act of reaching out, potentially, it touches people more directly than through the written word. Voice is limited to a place, at a specific time. It's intimate: one speaks, the other listens.
The understanding of the specifics of the artistic work process is still incomplete. Philosophers like Maurice Merleau-Ponty (on Paul Cézanne) or Gilles Deleuze (on Francis Bacon in 'The Logic of Sensation') have ventured into that realm. This competition is an attempt by a team of artists and scientists whom together are trying to come to a more profound and holistic understanding of the artistic process and its needs.
