Hey, I'm looking for the highest quality recordings from the following Artists:

Subjectively of course-If your talking LP's, always a sure bet to go with the period press.

Finding clean copies can be challenging.

Perhaps you're already checking discogs?

Billie Holiday | Discography | Discogs

Chet Baker | Discography | Discogs

Eva's recordings appear to be only on CD

Eva Cassidy | Discography | Discogs

Looking for vinyl for sure!

All three have vinyl  recordings on amazon.

Chet Bakers - Chet Baker Sings is the one I have my eye on.  There are a few different recordings. Have this on cd.

Not sure about Billie or Eva. 

TIA

Also, what's a period pass? 

Billie has a great cd titled Love Songs which I have on cd.  Bunch of vinyl on amazon. Tough to choose.

Same with Eva.

Period press that is...

Billies discography goes back to 78’s, but I’m guessing you’re not into that.

You want a particular album FROM the period it was released.

Example

Billie Holiday - Body And Soul | Releases | Discogs

This album released 1957.

Arguably, the 1st listing generally will be part of the initial run of pressings. It stands to reason it should be the "best" whatever that is.

I’m a period press fan for nostalgia AND what I think was the "best" SQ possible at that time.

I’ll surrender to reissues if an album in unobtanium due to price.

The mono vs stereo thing is also an unsettled argument. If it’s the period of Billie or Chet-mono for me.

Edit-there are some super LP afficionados in here..some will chime in with more detailed info
