This is Marco Aslan's beautiful video of life of the streets of São Paulo which condenses 3 hours of Sunday life into a 3 minute video.
To me it has a sort of dreamy quality to it. I think it manages to capture the loneliness and fragility of the centro region but retains an uplifting portrait of the human spirit.
It's called 3 horas em São Paulo and the music is by Ludovico Einaudi. Enjoy.
