Imagine a world in which there is no way to record music. Imagine a world in which there is no possibility to broadcast sound. A world without CDs, radio, cell phones that play mp3s, websites that stream music. A world in which music sounds only in live performances. Most people would find this world terribly boring, some might even say it is a life not worth living. Waking up in the morning without turning on the radio? Impossible! Having a beer at the local bar without music playing in the background? No way! We are surrounded by prerecorded music all our lives. Some of us have never experiences a live performance of music. A friend of mine who turned 30 last year had his first contact with live music two months ago! This is just unbelievable. Think about it for a moment: music plays an important role in almost everyone’s life and yet only a fraction of our society regularly attends concerts and other events in which music is performed.
