Best jazz or blues female vocalist ever


Hello, I'm looking for some recommendations for a female vocalist (blues or jazz) from before about 1965. I think that Ella Fitzgerald and Billie Holiday are contenders for "best". Could I get some recommendations of vocalists? Also, what works would you say is their best effort? Thanks in advance.

You need to hear SHirley Horn album,Here`s to Life.You are
missing out on a real gemm.
Thats a hard one to answer because at any given time a female singer with any good material will move you. But if I had to I would say Ella,Vaughan,Bessie Smith and Kelly Smith,Holiday and Washington. There are more just to early in the morning. Also try some Lena Horn not a true Blues or jazz singer but a fabulous voice. I guess we have to stick to he old standards becaue your not going to find them on American idol.
I'll second Rayhall's & IMO, her best was Clap Hands Here Comes Charlie -- EXCEPTIONAL!
