Modern day female jazz recommendations

Check out Frank Sinatra's Duets I & II, I know he's a he...but this disc has some great vocals with Carly Simon, Patti laBelle, Chrissie Hynde, Aretha, Barbara Streisand, Gloria Estefan, and on it goes, also there's a duet with Jimmy Buffet doing Mack the Knife. Very Cool... and I was NEVER a fan of the chairman, until now..go figure!
I would LOVE to hear Crissie Hynde do a "jazz" standards type disc!

I also picked up "The Best of Holly Cole". Very nice voice, some neat songs I had never heard as well as some covers like "I've just seen a face" and "Alison".
I'll probably look for some more Holly Cole too.

I am curious. As a result of this post has anyone gone out and purchased any of the artists that were recommended here?

If so how would you rate the artist?

I bought Susie Arioli and Tracey Kent. They are both fantastic artists. Tracey has a warm sultry voice. Arioli also has great voice and some well-recorded live stuff.

Would that be Stacey Kent? One of my favorites. Incidently, Stacey is in NYC at Birdland June 2-6.
