The Mp3 Experiment has become an annual event for Improv Everywhere; Agent Tyler Walker and I put an mp3 online (usually around 45 minutes long) and agents download and transfer it to their iPods. Everyone then synchronizes their watches to an atomic clock on the website, and then heads out to the same public location. At the predetermined time, everyone presses play. Hilarity ensues as participants carry out ridiculous instructions delivered to their headphones via narrator Steve (aka The Omnipotent Voice From Above) and folks passing by try to figure out why a mass of people are all silently jumping around.
This mission is sometimes confused with a “Silent Rave” or “Mobile Disco,” a type of flash mob popularized in England where mobbers arrive in a public place to dance silently to their own iPod. The key difference with our event is that everyone is actually listening to the exact same thing, which makes it all the more fun.
