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

Well, she's not a new sultry lady, she's an old one now, but she's the one that Diana Krall holds in high esteme, and in my estimation, trys to emulate (unsuccessfully), Shirley Horn. She's a bit more laid back but she's the real thing! She is an excellent piano player, singer, and stylist. Three CD's to start with - "I thought about you", "Close enough for love', and "You won't forget me". all on Verve.
Three other jazz current singers well worth listening to: Mary Stallings, Rene' Marie, and Tierney Sutton. These gals should be around a while judging from their current limited catalog (3 or 4 each).

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.

yma Sumac or something very close to that. I think her voice spanned 8 octaves!

Mary Stallings has been mentioned before. She has a new release "Rember Love" on Half Note Records. Some scat, some lush jazz renditions of standards. Excellent music, recording is very high quality. Good place to start if you haven't heard her yet.

Quick follow up - I can't edit worth a crap! The Stallings album is "Remember Love".
