Modern day female jazz recommendations

I don't know if you would call this jazz, some Bossa Nova in there and lots of big band but the guy is brilliant - Michael Bubl'e. Was never into this type of music until I heard one of his CDs, now I have them all......in the past month!!
Frank Sinatra style with a more intimate and romantic edge and lovely recordings. If you want to experiment don't get any live stuff (can't remember the name of my "live" CD). A lot more talent than Diana Krall and a bit more life to his music too. Interested to see if any of you are familiar.

Sorry about the above response....Bubl'e obviously isn't female.

I recommend Mina Agossi, the NOT wannabee like somebody else. You may want to try the "Simple Things" cd with her vocal interpretations of Pink Floyd and Jimi Hendrix songs

Roberta Gambarini,, has a vocal range and tonal purity that will remind you of Ella! Simply the best contemporary female jazz singer of a generation..

Been giving Sunny Sumter another spin as I found her first CD and then went back to her Larry Willis produced Mappleshade.
