The Mp3 Experiment by pranksters extraordinaire Improv Everywhere is taking place in San Francisco today @ 2:00 PM and tomorrow the same time at Chicago. The Mp3 Experiment is an annual organisation where you meet other agents at a predestined place and play a prerecorded mp3 at precisely the same time (you shouldn’t listen to the mp3 beforehand if you don’t want to spoil the fun!)

Accompanying track off Rollo’s (Atsuo of Boris fame) Pinhole album from 2006.

Update : Improv Everywhere has published the video for The Mp3 Experiment.
