Found footage, cut to a record
Conner was cutting stock footage to pop music in 1958. His later films for Devo, Brian Eno and David Byrne are often counted among the first music videos.
A Movie and Cosmic Ray treat found footage as raw material and the soundtrack as the spine, and cut on the beat so the images argue with each other.
In 1978 Conner made Mongoloid for Devo, and in 1981 Mea Culpa and America Is Waiting with music by Brian Eno and David Byrne.
