"Ephemeris" (2011) is a conversation of image and sound, between filmmaker Paul Clipson and electronic musician Aki Onda, rendered as if from a fragmented journey of landscapes and memories. Clipson and Onda each investigate very personal, intuitive spaces, through their favored technologies of Super 8mm film and cassette Walkman. Both artists base a significant emphasis of their work on performance environments, where their visual and sonic field recordings interact to create sensory collages born out of the subjective impressions of the audience.
