Thanks to a_muse_d
who turned me onto this. I like the song and I really like the simplicity and beauty of the video. However...
While the effects near the end were a nice touch, they left me feeling unfulfilled. We are introduced to a chorus of women (perhaps a class?) who are all doing some really beautiful work -- and unison movement can be very captivating when done right. Then their "teacher" takes the stage and I'm expecting to see her to do a virtuosic turn, building on and exceeding the level that has been set forth. But with the exception of her use of the train of her dress, it's not really anything over and above what her "students" have done. Until the CGI kicks in, which is almost immediately. But then it's not the performer's artistry or ability, it's some animator at a computer in post-production. If the soloist had established her virtuosity and then the CGI supported that, I think it would have been much more effective -- and artistic -- than the CGI becoming the differentiation between the "master" and the "student".
It's like old-school Jackie Chan vs. Hollywood wire-fu. With Jackie you always knew that you were watching a true master of movement at work. With the wire-fu, you know it's all of the technology at work and the performer mostly along for the ride. There's nothing special there.
