sexiest sounding female vocalists?

Marcy Levy singing on "Lay down Sally"

1962 recording of Shirley Horn singing the now politically incorrect "Do It Again.' Off the Loads of Love LP. I don't ordinarily find Horn all that sexy, but damn. Otherwise, Helen Merrill in general and Diana Krall's "Peel Me a Grape" (though I still prefer Blossom Dearie's version).

Right now for me, it's Annie Haslam. She was the lead singer for the 70's band Renaissance.

2 great albums and great site:

Nobody's mentioned Mavis Staples of the Staple Singers. True, she's supposed to be a gospel singer, but anyone who listens to her moaning about heavan and her ability to take you 'there', will understand immediately how easy it was for Ray Charles to turn gospel into the 'devil's music.' Gospel can be sexy! Sweet Honey in the Rock is another sexy female band.

also, I'm surprised that no one's mentioned Marilyn Monroe, the woman so extrordinary that unlike anyone mention on this board so far as uniquely carved a place for herself in the male psyche as THE sex symbol of the 20th century. Listen to her singing, "I want to be loved by you", "kiss" and "Do it again." Also Gillian Welch singing 'Miss Ohio' and Eartha Kitt singing, 'I want to be Evil."

Just a few of the greats.
