Location: Lawns Near Hudson River Park’s Pier 46 in the West Village (Specific starting areas on map below)

Time: The event starts at exactly 1:00:00 PM and lasts just over an hour.

What to Wear and Bring:

Wear: Dress in bright colors

Bring: A bag (purse, backpack, messenger bag, shopping bag, etc.) that has the following items inside:

– A $1 bill

– A trading card to trade (any kind. make your own if you don’t have one).

Download our smartphone app:

Mp3 Experiment iPhone/iPad App
Mp3 Experiment Android App

Open the app and click “join” for the Mp3 Experiment 21 event. Do this in advance; don’t wait until you are at the event. After you click join, you will see a countdown timer. The app, if open, will begin playing the audio track when the timer reaches zero. Bring headphones. Wired headphones are recommended if you have them to ensure no Bluetooth interference.

(If you do not own a smartphone and would like to download the mp3 file and sync manually, it’s on Soudcloud)

Location:

Our starting point is the grassy lawns in the upland area by the river between Charles Street and West 12th Street. See map below. Sit on any of the lawns and blend in (bring a picnic blanket or towel for your group if you like.) Spread out and use the lawns further north if it’s crowded.

When 1:00:00 PM Approaches

Make sure you have your headphones on and the app open. The track will play automatically at 1:00:00. When it starts, turn on “do not disturb,” turn off the screen, put your phone away, and have fun! Keep all of your props in your bag until you are asked to take them out.

If you are interrupted by a phone call during the event, just make sure to return to the Mp3 Experiment app and audio will resume playing in sync. If you have any sync issues, try turning “autoplay” off and then back on.

RSVP:

You can optionally RSVP on Partiful for updates. By RSVPing on Partiful we’ll be able to text you last minute info (like if there is a rain delay).
