Okay, I know most of you have probably already seen this. But just in case you hadn’t caught the original here is Eric Whitacre’s first “virtual choir” video. For those who aren’t familiar with the project, composer Eric Whitacre made a score he had written available to the public. He then asked people to watch a track of him conducting while they sing along, listening to an accompaniment track. He then took all the videos submitted and spliced them into one single choir.

It is pretty impressive.
