Over fifty years after the Situationist International appeared, its legacy continues to inspire activists, artists and theorists around the world. Such a legend has accrued to this movement that the story of the SI now demands to be told in a contemporary voice capable of putting it into the context of twenty-first-century struggles. Accessible to those who have only just discovered the Situationists and filled with new insights, The Beach Beneath the Street rereads the group’s history in the light of our contemporary experience of communications, architecture, and everyday life. The Situationists tried to escape the world of twentieth-century spectacle and failed in the attempt. Wark argues that they may still help us to escape the twenty-first century, while we still can.
