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

Glad you’re enjoying Emmylou, tonykay. There’s lots more to discover. She's been recording since the mid 70s. She is an artist who really reaches me on an emotional level and she’s a class act.

Warning for others, most of her music is classified as country. So if you hate country, skip it, but she just may change your mind.

How about  Julie London, Doris Day, and Judy Garland ?  Man, those girls were fantastic in the day.  Oh yes, there are more.
Wailin' Jenny's.   3 gals in one brilliant band. Look for the Live album, then play the last track: One Voice. Wonderful!
