Modern day female jazz recommendations

Mina Agossi has a very refreshing and different style

If Jane Monheit's musical selections were as terrific as her physical appearance, WOW, she'd be at the top of all the 'more lustful' male audiophiles on this site!

Speaking of babes with incredible voices, has any heard Carla Bruni? Unbelievable... and french!

Mary Beth Maziarz is pretty sweet though she might not fit into the jazz part.

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?
