Word on the street of San Paulo is that The Pixadores are about to go to war with the street artists.  These are pictures takin from an attack on  Galeria Choque Cultural (Cultural Shock Gallery) in protest of the marketing and institutionalization of street art.  There was said to be about 10,000 to 15,000 worth of damage to the space and the art work being displayed.  Peep Wooster Collective for more pics.  And for more on this topic click here
