Reuters reports that during Rage Against The Machine’s set on Friday at the three-day Voodoo Music Experience festival in New Orleans, frontman Zack de la Rocha said his visit to the poor and mostly African-American Ninth Ward neighborhood convinced him that the U.S. government was at war with New Orleans after Hurricane Katrina. “You represent all the beauty that still exists in this city. Wake up and fight them,” the singer told the mostly white audience.
