Having already made a video for their song Bear Claws, Irish indie-rock band The Academic have now devised a remarkable new way to present the song. It's resulted in the first 'live looper' video and a viral sensation.

And the ingenuity lies in the way they have exploited a technical anomaly. As the band explain before it starts, this is about the built-in delay that occurs when you use Facebook Live, before it appears on your Facebook page. The Academic have exploited this time lag to create loops, and then layered the loops to create a new version of the song.

Crucially, this all happens live, in one take. Of course it does - it's all on Facebook Live. And not only is this audio ingenuity, it also creates a unique visual perspective.

"We created a first-of-its-kind Facebook Live performance of our latest single, “Bear Claws,” using the audio/video time lag to create a mesmerizing visual loop sampler," explain The Academic (who presumably came up with this themselves) under the video on YouTube. 

"Here’s how: We rearranged each instrument on “Bear Claws” to fit Facebook Live’s delay, with each loop getting more complex, adding instruments, rhythms, and melodies. Additionally, by projecting the video live from a soundstage we created an infinite tunnel consisting of all the previously recorded loops."

Genuinely mindblowing stuff.
