Dutch sites have been posting the RSD list for 2021.
I just did a run through to pull out some of the jazz releases:
Barney Wilen - La Note Bleue A 2LP set.
Bill Evans - Behind the Dikes: The 1969 Netherlands Recordings A 3LP set from Elemental. I smell Zev Feldman's involvement.
Charlie Parker - Bird In LA A 4LP set.
Chet Baker - Cool Cat This link actually has a lot of info.
Frank Foster - Loud Minority
John Coltrane - Naima / My Favorite Things Not too sure what this is, I think its just a 12" single?
Kenny Dorham - Quiet Kenny Another unknown, just looks like a reissue?
Miles Davis Miles Davis Champions From The Complete Jack Johnson Sessions. I mentioned this before. @Poly-Rythmo the colour is awful.
Rahsaan Kirk Roland Live At Ronnie THIS IS KILLER! I haven't heard of the label before but this session is going to be blinding, it's legendary!
Salah Ragab & Cairo Jazz Egypt Strut This looks really interesting, going to dig deeper into it.
Thelonious Monk Palo Alto: The Custodian’s Mix They seem to be really milking this one.
Various Soho Scene ’67 (Jazz Goes Mod) I believe this is part of a series, with one set being released last year as well.
I think the Charlie Parker was originally slated for last year, there's a bit of info here:
The Bird 100 centenntial centered around the life of jazz icon Charlie Parker continues with a graphic novel and numerous vinyl releases.
