The concept of a test is inherent in Kren’s Experiment with Synthetic Sound (Test), which is really a kind of endurance test to which Kren subjects the film material and the eye. The film makes do with a minimum of image content (a wall, a cactus) and modulates them temporally over a strict strophic arrangement that doesn’t stretch these motifs into the imaginary realm of images but lets them exist in their own “superficiality”. The sound, which is scratched directly onto the material, corresponds with this principle in that it allows only crackling and scratching noises to be audible, expresses itself in unmodulated, raw stretches of sound and noise.
