Watch Sadisflix. Exploring the musical concept of "release," this film is a haunting found-footage study in the plurality of visual and auditory meanings of the term. A series of collaborative works pairing artists working in visual and auditory mediums, the Études meditate on individual musical concepts through experiments with sound and film. Étude 1a: Release (I) is the first in this series and is directed by filmmaker Russell Sheaffer and composer Aaron Michael Smith.
