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.

She's none of the above, but give either of Julia Fordam's first two cd's a try and you'll see why her 19 year old cd Porcelain made Stereophile's "Records to Die For" this year.
