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

One I haven't seen mentioned is Jacquie Naylor. "Live from the Plush Room" is a good place to start.

Second (or Third or 95th) the recommendations of Eva Cassidy "Live at Blues Alley," Cassandra Wilson (have four discs and all are great), Christy Baron, Patricia Barber (her cover of "Light My Fire" might be the five sexiest minutes of music I own), Madeleine Peyroux (esp. "Hey Sweet Man") and, of course, the great Ella (especially her duets with Louis Armstrong). Good listening.

Cai Qin. She is a chinese vocalist and is awesome. While you wont understand the words, no need. The music is beautiful and so are the sonics. You can probably get it outside of Hong Kong in Chinese music stores in places where there are chinese vendors, chinatown, etc. JVC I think makes and XRCD of this. I believe the CD number is 7243 5 32378 20. I know Chinese audiophiles use this alot for demonstration. It was even playing in a famous chinese movie in a high end audio store for one scene. I am not Chinese but my wife is. I learned about her from a work associate in Taiwan. Another good chinese vocalist is Teresa Teng. You wont understand the words but trust me, the music, voice and sonics on most CD's are good.

Sarah Vaughn, Rosemary Clooney, Dinah Washington

Madeleine Peyroux.
