This is a massive breakthrough. We are standing on the cusp of a huge materials revolution. And it’s very gratifying to know that in you we have a sculptor who is at the cutting edge of science. What is materiality? It’s not just what we are already familiar with from Beuys and other artists – extracting the mystical significance, the historical significance, and remembering what something could mean when we look at material. It is gratifying that in Martin Walde we have someone who clearly recognises the future significance of materiality through his artistic work.
