I'm always blown away by the power and feeling in Betty's voice. She's an answer to "Who could you listen to singing the phone book?". She's not just one of the best female vocalists on the indie scene, she's one of the best female singers I can name, ever.
Then there's Patrick. Guitar isn't just a skill, it's an art. You have to know how to use it. Don't just always play fast because it sounds flashy. Play with feeling. He can do both and he knows exactly when and how to play to perfection.
