Should I listen to the track beforehand?


Can I listen to the track beforehand?

You really shouldn’t. Sure, there’s nothing we can do to stop you, but to really get the full experience of the event, you shouldn’t listen to it. It will spoil most of the fun. We know it’s hard to resist. Be strong.

What if I get to the event late?

Press play at the start time wherever you may be, and hurry up! Obviously be safe and don’t rush when crossing streets, etc.

What if I don’t press play at exactly the right time?

If you can tell you are significantly off, feel free to glance at a neighbor’s device and try to sync back up to the correct time. You’ll have more fun if you’re more in sync.
