A video containing two pieces of music in which the speed has been adjusted beforehand. The music before adjustment is reproduced by showing a single film at three different speeds, normal, slow and fast. This is an attempt to extract three kinds of times from a single time.

The super tweeter (loudspeaker device for ultra high frequencies) plays music in fast forward while the sub woofer (loudspeaker device for ultra low frequencies) plays music slowly. Their pitches are modified so much that you cannot find out the original any longer. The speaker set is videotaped with surrounding scenes. The music is recovered by speeding up or down the video, which, however, cannot help but modify the videotaped scenes relatively.
