With the film Sun in Your Head, Vostell translates the principle of dé-coll/age to the moving image. Because there is no video technology available in 1963, the cameraman Edo Jansen films distorted television images from a screen. The film is reedited in 1967 and copied onto a video format. The first screening takes place at the Yam Festival, May 19, 1963, held on a farm in South Brunswick, New Jersey, and organized by the Smolin Gallery. The second screening is part of the happening 9 Nein Dé-coll/agen on September 14, 1963, in cooperation with Galerie Parnass.
