I've heard them all. Maria is the best ever! Even my 72 year old grammy who liked Barbara Streisand thinks Maria is better than any of them ever where. Maria is the end! I'm talking going beyond her screaming. It's her singing! I love her so much! I love everything she does and the way she does it! I went to see "in this moment" 2 months ago and freaked! I'm so glad I got to see them! As far as I'm concerned, all the other female vocalists are fired! JK, I like the others but they just cannot compare to Maria.
