The Academic Use Delay From Facebook Live to Loop a Song

The Academic used the delay from a Facebook Live recording to loop their song. Mashable explains, but it’s really worth seeing:

It’s a little easier to understand if you actually see it in action, but essentially, the band performs for a Facebook Live feed that’s then projected behind them. They manage to sync up and perform with the same delayed feed a few seconds later, and as the song progresses, it gets more and more interesting.
