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

Lizz Wright, Nina Simone!

Tierney Sutton: Green in Blue, Introducing Tierney Sutton. She really uses her voice as an instrument and knows how to do it. Amazing stuff.

Stacey Kent: Let Yourself Go. Very fun collection of Fred Astaire tunes that swings with great piano. I never tire of this CD.

Nancy Wilson: Her records with Cannonball Adderly and George Shearing. Stunningly beautiful voice, perfect control, and gorgeous. The complete package.

Ella with Louis Armstrong: What a pair! And do not underestimate Louis as a jazz singer.

If I may suggest a male singer, Joe Williams: His album with Count Basie is fabulous.

I file it in Jazz, but others put it elsewhere and it's recorded on rounder, but none the less I can strongly recommend the new Madeline Peyroux - Carless Love. I think samples are available at towerrecords.com

I fully agree with R burke.The new Madeline Peyroux is brilliant as also KD Laing - Hymns of the 49th parallel, though not jazz,both are Stereophile recordings of the month.KD Laing does an ethereal interpretation of standard Neil Young& Cohen classics.Hugely recommended.

Having listened to Krall since her 'All for You' album, I was very disappointed when I saw her live a couple of years ago just going through the motions and showing very little if any passion.

Some great suggestions above but I'm surprised no-one has mentioned Ute Lemper on the Jazz/cabaret style. You can feel the passion in her singing and I was nearly in tears at the end of her concert in Paris (promoting her 'But one day...' album)

Another favorite of mine is Montserrat Figueras a cantatrice with a magnificent voice (part of Hesperion XXI group) singing mainly Hispanic ancient music if you can handle this type of music.
