Music video from before 2020
Back in high school, my choir teacher showed us a music video of what I think was a choral piece. I cannot remember the lyrics, melody, or artist. The only things I remember is that it was a choir consisting of a high number of people, possibly up to a million, each person recording themselves singing their part. It had a 3D animated city scape that had the people who were singing where the windows would be. And the final thing I can remember is that it had a girl, also 3D animated, that grows wings and flies through the city.
Edit: I found it, like, 10 minutes after posting this. The song is Fly to Paradise, sung by Eric Whitacre's virtual choir. The actual number of people singing is just over 5,000, not a million. I'm honestly not sure where I got the million from. This is the video on YouTube.
