Can anyone recommend me some 60s/70s Blues female singers?

Cant believe no ones mentioned the best all time Blues singer in the world. EVER! Ella Fitzgerald. Nina Simone / Billie Holiday Getta hold of the CD 'The Lady Singes The Blues' various artists. Brill.

Christine Perfect (Chicken Shack). If her version of "I'd Rather Go Blind" doesn't send chills up your spin - you must be dead!! And what D*pSh*t is handing out the "thumbs down" - it's people's personal opinion and we're not in Nazi Germany

Janis Joplin by far is the best, she sings me and bobby mgee summertime mercedes benze and many others that are just as good i really recommend her, i actually was janis for halloween one year, she loved southern comfort, that is my favorite drink as well, but died from an overdose on heroin, i don't do drugs too bad she couldn't have lived long enough to make more great music, i suggest that you get her greatest hits album she said, and i quote "as they say on the train, it is all the same damn day"
