Which female artist


Hi all
Just wanting to know if anyone can add to my list, of similar sounding female singers.Here goes , just to start the ball rolling.
Gretchen Lieberum "brand new morning"
Rickie Lee Jones "priates , flying cowboys , the magazine"
Dido " life for rent , safe trip home ( my favourite at the moment )
Mary Chapin Carpenter " between here and gone"
Kathyrn Williams " dog leap stairs , old low light "
Any help of finding new female singers , or even similar male singers, would be great .As always looking for somthing new to listen to

Shelby Lynne "just a little lovin" absolutely sublime

Tierney Sutton "Dancing in the Dark" why never mentioned anymore???

Oleta Adams "Circle of One" no one remebers this great album

Nora Jones "Come Away with Me" just because it sold 15 million copies does not mean it's not good
I would also highly recommend Jennifer Warnes (The Hunter, The Well and Famous Blue Rain Coat). But I am also surprised that no one has mentioned Mary Black, one of my all time favorites. I especially like No Frontiers and Holy Ground, but almost anything she did when Declan Sinnot was with her is outstanding in my opinion.
Here's a few more:

kd lang - Hymns of the 49th parallel
