'Walk On' is the first exhibition to examine the astonishingly varied ways in which artists since the 1960s have undertaken a seemingly universal act - taking a walk - as their means to create new types of art. The exhibition offers an as-yet-unwritten history of recent art practice. It proposes that, across all four of the last decades, artists have worked as kinds of explorers, whether making their marks on rural wildernesses or acting as urban expeditionaries. It argues that from land art to conceptual art, and from street photography to the essay-film, much of the important art of our time has been created through an act of walking.
