Song #1 was Mariah Carey’s “My All” and it was her best performance of the season. As J-Lo said, we’ve heard her do the growling and shouting and the Jennifer Hudson stuff, so this was a real treat and a reminder …oh, right, Jessica Sanchez is one helluva a singer and her voice is a perfectly tuned instrument capable of things not many other vocal chords can do. Like, the world is full of “big voices” that can hit those super high notes, but it’s rare when you hear a voice that can hit notes all over the scales, in rapid succession, so that their voice rivals a piano or a violin …moving every which way and that. It was incredible. Hopefully everyone loved it so much they didn’t pay attention to her next two songs.
