Radical Nature - Art and Architecture for a Changing Planet 1969–2009 exhibition is on at the Barbican Art Gallery until the 18th October 2009.
'Radical Nature draws on ideas that have emerged out of Land Art, environmental activism, experimental architecture and utopianism. The exhibition is designed as one fantastical landscape, with each piece introducing into the gallery space a dramatic portion of nature. Work by pioneering figures such as the architectural collective Ant Farm and visionary architect Richard Buckminster Fuller, artists Joseph Beuys, Agnes Denes, Hans Haacke and Robert Smithson are shown alongside pieces by a younger generation of practitioners including Heather and Ivan Morison, R&Sie(n), Philippe Rahm architects and Simon Starling. Radical Nature also features specially commissioned and restaged historical installations, some of which are located in the outdoor spaces around the Barbican while a satellite project by the architectural collective EXYZT is situated off site.'
