I have always had a thing for Shara Worden's (aka My Brightest Diamond) voice. She is a trained opera singer with an amazing range and depth as well as texture, though I do not know if she's a coloratura soprano. I first fell in love with Gone Away, one of the best songs to slash your wrist by when pining for a former lover. But what she executed in this video is both cute and awesome and I think you will agree with me that it takes amazing lungs to sing this flawlessly while stamping as hard as she did.
