The audio walk Glückliche Zeiten (Happy Times) invited people to take a walk into the world of competition and horse betting as part of the Open Source Festival 2019 that took place on a Düsseldorf race course. How can the value of a racehorse or a musical act be measured? How does value arise, how does it increase, how does it decay? What does it take to predict the downfall of a matador, a football club or a musical event? How do I deal with the disappointment when my horse, my band or the audio work I am listening to does not live up to my expectations? Doesn't feel like going on any more? What to do if I bet on the wrong horse? What if the competitor blows for surrender? Glückliche Zeiten, audio walk, 2019
