BEST FEMALE VOCAL EVER


HELLO TO ALL...

I've started a BEST MALE VOCAL seperately - if you want to contribute to that, please go that discussion...

I personally think the BEST FEMALE is so much harder than the Best Male, and I already have so many names in mind that I thought I'd wait and see others suggestions.

SO PLEASE OFFER YOU HUMBLE OPINION - BUT PLEASE, offer only one.

THANKS to all who cotribute...

Also assuming popular music (as opposed to classical) I am a sucker for the throaty (and sometimes quavery) voice of Stevie Nicks. May not have the range of so many great entries above but she is my pick for this forum.
I want to add to my previous post of only four words about Eva Cassidy.
She could sing in just about any style.
You couldn’t categorize her. 
That was one of the reasons I believe she did not make it big while she was alive.
Yet she was extraordinary in every style.
She had a seemingly limitless vocal range, and an emotional impact like an atomic bomb.
Yep. I was being a bit PC, i.e. not being too effusive, but she is my favorite vocalist by a mile. Other can be beautiful etc, but she can bring tears to my eyes! :-)
