Michael Snow's film "Wavelength" is one of the most important avant-garde works of the second half of the 20th century, in which the "narrative" is composed of a static and gradually zooming in shot lasting 45 minutes. It highlights the main themes of Snow's work such as questions about the nature of vision, the sensory experience of the material world, and the relationship between vision and sound. Similarly to Michael Snow's film "Wavelength" (1967), the form of "(Back and Forth)" is deceptively simple: the camera moves forward and backward, capturing an abandoned and poorly lit classroom. However, over time its effect leads to questioning the nature of cinema itself, the images, and the act of viewing.
