Inspired by a lesson from Erik Satie; a film in the form of a street - Castro Street running by the Standard Oil Refinery in Richmond, California ... switch engines on one side and refinery tanks, stacks and buildings on the other - the street and film, ending at a red lumber company. All visual and sound elements from the street, progressing from the beginning to the end of the street, one side is black-and-white (secondary), and one side is colour - like male and female elements. The emergence of a long switch-engine shot (black-and-white solo) is to the filmmaker the essential of consciousness.
