It's a known fact that I'm awfully fond of YouTube artists. I think it takes a lot of courage to post videos of yourself singing for all the world to see in the hopes of being discovered and having to deal with critics who don't appreciate what you do. A friend recently linked me to this pair, and it's a cover of a song I really love. I think they did it brilliantly.
I give you, Just A Dream - Christina Grimmie & Sam Tsui, enjoy!
