This is pretty impressive.
What makes it so impressive is that it is performed.... by a computer. The singing voice is entirely synthesized. By a sythesized voice that is extremely popular in Japan called Hatune Mikue which supposedly means future voice. It's so popular there that the Japanese Space Agency engraved her avatar on one of the plates they sent up in the probe that recently entered Vensus's orbit five years after the first attempt failed. There are tens of thousands of synthesized songs like this performed by this voice. I can't imagine any other one being advanced enough to do this believably like this.
