If you haven't heard of the AMAZING acapella group Pentatonix, you really need to watch this video.

Not only does it showcase their incredible vocal talents (there are NO instruments used in this entire video), but they join forces with YouTuber Todrick Hall, also known for his singing and film-making, to retell the story of Dorothy, Toto, and the rest of the characters in the land of Oz.

You won't believe how good this is!
