I still remember the feeling I had the first time I heard Ingrid Michaelson sing. I was in New York City on vacation. I was on a treadmill in my hotel and she was on Regis and Kelly. I stopped the run because I was blown away. It wasn't anything remarkable, it was, however, fresh. I wondered why no one had thought of her songs before her.
That's the same feeling I'm having listening to Christina Perri. You've heard her song "Jar of Hearts". What you haven't heard is the versatility of her music on the full album. Download "Miles", "Bang, Bang, Bang", and the "Arms" video.
