Since its formation in 1987, Critical Art Ensemble has set out to explore the intersections between art, critical theory, technology and political activism. The award-winning group of tactical media practitioners has exhibited and performed in a variety of venues internationally, from the street to the museum to the internet. "Disturbances" is the first book to assess the group's 25-year history, examining the environmental, political and bio-technological themes of their various initiatives.In the publication, each project is presented by the group itself, from their early live multimedia productions; to their development of models of electronic civil disobedience, digital resistance, and contestational biology and ecology; to their most recent tactical media projects."Disturbances" is a landmark handbook for activists in art, theory, science and politics.
