I need a female jazz vocalist. No Krall, No Norah

Nina Simone, the earlier the better...

Try Etta Jones (not the same as Etta James). Lonely & Blue is the album I know.

Eva Cassidy Super recording "Live at Blues Alley"

Thanks for the Tierney Sutton. I really like her voice.
Which one of her CD's should I get?

I would suggest that you start in the order they were published, "Introducing Tierney Sutton" on A-Records, "Unsung Heros" on Telarc, and "Blue on Green" also on Telarc (this is only because I totally enjoy the first two and don't feel quite as connected to the last.) Although you didn't ask for more recommendations, since you like Tierney Sutton, you might give Karrin Allyson a listen. I actually enjoy her more. I would suggest as a good place to start to get a general feel would be "Daydream" on Concord Jazz.
