Santiago Sierra (Madrid, 1966) is one of the most controversial artists in the international art scene. He has become famous for his critique of the contractual economy through a series of remunerated actions where people – typically immigrants, casual workers, or even homeless wanderers – are paid to perform some pointless task which is then documented on video and through black-and-white photographs.
