Their mom is an opera singer and their dad is a professor for music. They are sisters and won that season back then. You need to see the other shows with them and the battles.
I love you saying "get your ass up"...that judge got embarrassed here. I do not agree with your view on the one at the piano not being as strong. I feel she was exquisite at her role and allowing the voice with maybe more controversy coming out in its fullest potential possible. I think the overall beauty and strength of these two girls is to recognize their unparalleled talents and their ability to hold our souls hostage to their next note......
