Download the audio file using our app:

Mp3 Experiment iPhone App / Mp3 Experiment Android App

In the app, select the Riverfest event(s) you plan to attend (June 1 or June 6), and click “Download” to join the event and download the file. After the file downloads, you will see a countdown timer. The app, if open, will play the track automatically at the right time when the timer reaches zero.

Please note: You should download the file in advance over a fast Wi-Fi connection. Do not wait until you are at the event to attempt to download.


The event is happening in two locations simultaneously. Choose either one.

– Kennedy Plaza (large plaza outside of Century II Convention Hall located at 225 W. Douglas)


– Redguard Stage Area at 350 W. Waterman

As the start time approaches, blend in with the area naturally as if nothing is up.

When the start time approaches

Make sure you have the app open and the track will play automatically at the correct time. Don’t forget to download the track in advance over Wi-Fi.

Do not use other apps on your phone during the experiment as they could interrupt playback. When it starts, turn off the screen and put your phone away and have fun!
