Watch 123Movies. Chicago's summertime blazes, unanchored. Skywriting out of time. Part of a series of nighttime long exposures, Blue Loop, July creates an odd document of a long-standing celebratory tradition in one of Chicago's lower west side neighborhoods. By leaving the camera's shutter open for seconds at a time, the film transforms a summertime spectacle into a light-trace animation that unseats reliability of spatial and temporal direction.
