They're going on and on about innovation and making "sound fall from the sky above the performer" and all I can think about the whiole time is "Yeah, but you've got a stack of freaking noisy, buzzing propellers all around your head. How does that not utterly destroy all your sound fidelity?"

I had to laugh when I came across this further down:
"the team is grappling with several issues. As of now, the drones’ propellers are still somewhat noisy. "

Lol. Yeah, I bet they are!
