Rick Rolled by 100-Voices

Some of us have a lot of extra time on our hands lately, but some more than others. Prepared to be Rick Rolled by 100 voices. Some guy did a video where he layered 100 vocal tracks of himself singing Rick Astley's "Never Gonna Give You UP." It's kinda of interesting. He starts out with four voices layered together and then keeps increasing the layers until he hits 100.  Included in the layering process is a high pitched whistle-tone, throat singing, opera style, and even heavy metal screamers. Enjoy!
