The edition "A Piano Plays In Another Room And It's Raining" contains the video files and a sound file extension. The video (16:30 min) is to be played in a loop with credits. The installation version contains only the sound effects. The piano music is meant to be played separately from the video. The sound file (120 min) is included. Both files are played in parallel, so that with each new loop a variation of the film music is created. On request and for long-term installations, it is possible to install a Mac mini with Ableton Live, which allows to play a continuously changing track.
