Most underrated female recording artists..

Christina Rosenvinge

Joanie Sommers - the biggest range and the most beautiful voice for sure, I have ever heard

Frazey Ford - the indie queen

Sally Carr - no words, her voice will do it

I saw some Hungarian names: Zsuzsa Cserhati was a super-talent, and Zalatnay a distant 2nd, and a whirlwind, nevertheless, 

Tiana Lemnitz and for those of you who’ve never ever heard of her;

Because I mentioned Tiana Lemnitz who was a prominent Nazi, I feel compelled to add that I know she associated herself with the Nazi view early on. Whether or not she did this to find work or whether she honestly believed in the demagoguery, I make it a rule to generally give artists some extra latitude in this regard. Herbert von Karajan joined the party twice and was not an anti semite. Alfred Cortot assisted the Nazi’s during the invasion of France but he was just considered a coward. Given the nature of the music profession, I believe artists were extremely vulnerable a afraid and rightly so. It was a deceptive time with some horrible things that were either kept hidden or ignored. It is difficult for me to recommend a former Nazi but her artistry is so impressive that I mention her for that reason alone.

Not sure I am onboard with your selection @goofyfoot in fact I am behind the boat on water skis wondering how this thread just " jumped the shark" to a prominent fascist. Fascism by definition is a forcible suppression of opposition so I am not going out on a limb here that Tiana Lemnitz did not face much of it until after May 1945.
