Although it's not the first time You Tube has live-streamed a concert, the controllable 360-degree camera bit is certainly interesting.
The concert video below is from the Director's Cam view.
BFI London Film Festival is Britain’s leading film event and one of the world’s oldest film festivals.
It introduces the finest new British and international films to an expanding London and UK-wide audience.
Just go to the American Express Unstaged You Tube channel and select from one of the many camera views to begin watching.
The 360-degree camera is honestly a bit nauseating to navigate, but it is definitely fun to try and even allows viewers to capture an on-screen photo of the concert and share it with Twitter, Facebook and Google+.
Other available camera views include a Director's Cam, "Fred Cam" and Backstage Cam.Actor, comedian and drummer Fred Armisen is directing the concert. Read: U2 concert to be broadcast live on You Tube The concert officially kicked off at 9pm GMT on Friday 9 August.
