This was the first thing I'd heard by either of them. Hadn't even heard about them, then one day during Christmas vacation I was bored and looking for stuff on youtube. This came up. Basically my jaw hit the floor. I spent the next two hours discovering them. Huge fan of both now.
Not to compare her to Garth Brooks but they are very similar in the fact that if you ever get the chance to watch them live, when you walk out of the show you know without a doubt that they did not leave anything on the stage. They sing with every ounce of their being. She burns the house down every time.
