Modern day female jazz recommendations

To call some of these people Jazz performers stretches my definition a little. Don't get me wrong, I love virtually all of them, if not their music, but I'd have to say that when I think of Jazz female vocalists, Ella comes to mind, Sassy Sarah, Billie; after that, there are select few.
Maybe its because Ella sang improvisationally, as did Sarah some, but the rest just touch the outer edges, at least, to me.
As much as I love Buble's music, I don't think of Jazz when I think of him--more of old standards with Big Bands to the rear. Obviously I'm wrong as he's listed in the Jazz bins and charts.
Anyone else see this distinction?

Rachael Price. I just picked up a re-released 2008 CD originally recorded in 2003 by the then 17 year old Rachael Price. Ella influenced with a beautiful voice can't wait to get some of her current work.

Try Paula West.

Samhar I saw your post mentioning Nnenna Freelon. The folks here just don't seem to understand. Finally someone else other than me acknowledges what a jazz vocal talent she is. Her voice is one of the best jazz voices out there today but few members here seem to get it...

At least we understand!
