Now it is clear to me why she was considered as one of the world's finest---having the powerful voice and "perfect pitch".
Way beyond that, what makes her deserve the Tony Awards and what makes the world got captivated is the way she sings, as if she has a very crucial message to tell and one ought to listen to her story.
She wants you to feel the pain, the sorrow and the wonders of how human should live. All of her performances made me hop from one musical/broadway/stage production to another. From Cats, West Side Story, Miss Saigon, Disney OSTs to Les Misérables. It was one of those nights that I can tell to myself: "i am having the BEST night of my life"
Truly, it was a musical treat.
