Sound on the Ground is a sculptural work installed with sound work, Happily, which deals with the question: What is the criteria of a story with a happy ending? As if it was dropped or forgotten, visitors can find an mp3 player on the piece of ground, which is connected to a hidden speaker via bluetooth. They are able to touch the screen of the mp3 player on the ground to play a selection of sounds. Each sound work is based on a text, which is written by Swan Lee or quoted from another author and transformed into an intro song with lyrics in ever after. A machine voice tells two stories, in Suicideshop (feat. jean teule), summsummboombomb_mixdown, and a theme song for both stories, theend.
