This got me thinking, “What is music?” Masterpieces such as this are called music, so is avant-garde noise. You could dress like a bunch of emo vampires and vent your ten years of frustration into the microphone, and that could be music, too. Is music art? If so, these things would fit right in.
Shout at strangers on the street, and you’re disturbing the peace. Do it on a stage, and you’re a musician.
