Lap dissolves have lost much of the appeal they had back when Citizen Kane (1941) introduced the Xanadu manse through an ominous series of overlapping images, each fading out as the subsequent one faded in, or when La Jetee (1962) utilized the transition for a more subjective sequence in which, according to the narrator, "images begin to ooze like confessions.
Similar layerings occur in the films, in which lap dissolves repeatedly interpenetrate one image into another, and in the spoken-word recordings, where hesitancies and loopings multiply the single voice.
