Good Jazz/Vocal Reference CD Recommendations?

Here is one more. This is not a reference quality recording sonically, but it is very, very good even by today's standards.

"Alexandria the Great" Lorez Alexandria

This is a reissue of a recording originally done in the 60's, I believe, by a relatively unknown jazz singer.
She has a wonderful voice which is clear and sweet, but doesn't lack for jazz phrasing like some of the current top selling female vocalists of today. I heard this CD in the record store over their sound system and I knew that I had to get it. I wondered who is this woman and why I never had ever heard of her before. In my opinion, she ought to rank in the top 10 jazz singers of the last 50 years, based on her performance on this CD alone. As I indicated, the CD is not reference sonic quality by today's standard, but very, very good.

Stacey Kent - although I prefer the music on "Let Yourself Go," the recording of "Dreamsville" is just gorgeous.

"Belly of the Sun" - Cassandra Wilson is good.
However these two will always be a part of my listening preferences:
"Homage to Duke" - Dave Grusin
"The Gershwin Connection" Dave Grusin

And surprisingly I really enjoy (well recorded) Willie Nelson's album "Across the Borderline"
I'm NOT a country fan.
