Anyone else never get tired of Billie Holiday?

She’s my all time favorite vocalist.

Anyone have recommendations for specific recordings?

I prefer her older work and picked up this.
The Verve collection from the 1990's was one of the nicest CD collections ever produced, mostly due to Phil Schaap. If you can find the original set, you'll be in for a treat. Later editions lack all the details and extras.
Here is a listing for one:
Im a big fan, but only ever had her greatest hits cd which Ive had for at least 20 years. Recently I bought her Ultimate Collection (Amazon), a 3 disc set. Fabulous
I never "get tired" of BH but have to be in the right mood since she sings with such overwhelming emotion. I can't think of anyone else like her.
I should add that the Verve set I mentioned has a lot of outtakes and studio ramblings. Some might find it annoying, but hearing Billie sing 'My Yiddishe Mama' to her child was pretty neat.
Of course, if you don't want to buy that set, you can definitely stream it on Qobuz. You'll get the finished albums without the outtakes.
In terms of the artistry and raw power of the emotions she conveyed, there are few artists that compare to her.  On top of that, her voice was pretty unique. 

The only artist with a similar voice was Marilyn Moore.  Ms. Moore only recorded one album, but, it is something that can be found quite easily.  I believe it was called "Moody Marilyn Moore."
One of the rare other black woman voice that are  pulsating nuclear emotions from the heart is Marian Anderson...Listen to "deep river" for example and at least call that a tie with Billie Holiday... The differences is that Marian can signs Verdi Schubert Bach or a negro spiritual with the same amazing weigh...It is the only one I put higher than any other voice except a very few including all opera white woman singers...

For example compare Schubert ave maria with Marian and with Jessye Norman....My choice is immediate for the pure perfection and devotion, she wins....I dream of "strange" fruit" sing by Marian...Billie Holiday is also able to convey the pure wave from one heart to another...Ella Fitzgerald for sure also...And some very rare others... 
The first time I heard Billie Holiday was while watching 9 1/2 Weeks. Mickey Rourke put on an album with her singing Strange Fruit. I bought the Columbia set when it came out. Excellent collection. 
BTW, Moody Marilyn Moore is available on Tidal. I have it saved as a favorite.

I dig 'Songs for Distingué Lovers' the bestest. Dig also 'Body & Soul' also 'Music for Torching.'
