A video about the Situationist International movement 1957 to 1972. Guy Debord is the key figure.
From the film:
They wanted to not only negate art but to also realize it, which is to say make of daily life a creative, continuously original, delirious, ecstatic experience.
It was interested in the construction of moments of life, and in replacing passivity and doubt with playful affirmation.
Greil Marcus: The situationists had two techniques that they believed were keys to changing the world /…/ One was the derive, which means the drift. And that meant people wandering through cities, being simply pulled by the attractions that you could find in the city or repulsed by things that were ugly and hateful. Simply letting the city itself, its streets, its buildings, its ambience, its mini climates, guide you, draw you down, making you see the city lived in, in an utterly new way. This was the way of discovering utopia, of discovering what you hated, what you loved.
Another technique was detournement, which was cut up, which was collage, which was juxtaposition, which was the refusal of original creation. It is the belief that everything that needed to be said was already there waiting to be picked up. It only needed to be put together in new ways in order to see the world in new ways.
