Best female vocal recording on CD?


i am a sucker for great warm rich smooth female vocalists, especially on tube gear and speakers that image well. but i am almost always faced with a great voice/song but a sonically inferior recording (examples too numerous to list) or a great recording of a mediocre voice.  rickie lee jones (pop pop) comes to mind- fab recording, but come on lets be honest about her voice. however, i will almost always pick great recordings and leave the bad recordings for the car.

 so i am asking for what you use as a reference female vocal recording/track. right now i come back tp bonnie raitt "you cant make me love you" from luck of the draw.  big, warm, strong voice. not a perfect recording. but hmmmm that voice.

my only requirement is it has to be on CD. and we all know of great vinyl that did not translate into great CDs.  so help me out here, what should be my next music purchase

All CDs. Fine voices, arrangements, performances and recording production (not heavy handed post production).  Probably a few more that I can't recall. I am retired, music plays 12-16 hours every day when I am home. I have a 4K plus CD collection (and vinyl which I rarely bother with) which is a drop in the bucket of talent. I felt guilty mentioning these folks because there are so many others.
