There are two main starting-points in the videowork interrupt: a selected, singular tone for the audio track and a single black bar for the video track. The video is edited according to a strict metric system in which the audio- and video track have the same numbers of cadres. The singular tone temporally structures the appearance of the picture. 'interrupt' has to be analysed; how can image structures and samples be developed with formal ideas like interruption, repetition or compression. Reducing sound to its individual pure tone - only divided into different cadre lengths - musically leads to interesting sound compositions, which are all based on the principle of interruption.
