Undercover performers listening to synchronized instructions in Hudson River Park in our annual audio adventure.
Full Story: improveverywhere.com/2025/08/06/the-mp3-experiment-twenty
For our latest mission, thousands of people followed secret, synchronized instructions delivered via headphones at Hudson River Park's Piers 62, 63, and 64. At exactly 2 PM the audio track began playing in everyone's headphones, powered by our smartphone app.
After surprising random strangers in the area with a series of activities like freezing in place, laying on the ground, and giving high fives, participants convened at the lawn in the middle of the piers for a picnic, freeze tag, dancing, and a spray bottle battle.
This was all part of our Twentieth annual Mp3 Experiment event, held every summer in New York City and toured around the world.
We support this free event by touring it to schools, festivals, and conferences. If you want to hire us to stage one for your organization, see here for more details and how to get in touch: improveverywhere.com/mp3-experiment
The Mp3 Experiment is created each year by Charlie Todd and Tyler Walker. All music is by Tyler Walker. (tylerwalkermusic.com/)
A huge thanks to the amazing community of people that continue to come out to be a part of this event every year. We’re so proud of what a diverse, joyful celebration the Mp3 Experiment has become. As silly as the project is, it’s life-affirming to be in a crowd of strangers, all smiling, laughing, and working together.
