Raw + Material = Art, By Tristan Manco

Anyone who labours under the delusion that Britain is still the HQ of modern art should invest a modest sum in this international survey of artworks utilising the "found, scavenged and upcycled".

Composed of gorgeous filaments, the paper clouds of Brooklyn-based Mia Pearlman billow from walls and ceilings.

Klaus Dauven's vast flowers transform a dam wall in Japan with "arguably the largest drawing in the world".

The works are so impressive on the page that one lusts to see them in the wood, paper or metal.
