@kirkwallace just asked Gemini, and here’s the answer I received…and based on it and info on Tidal, KG didn’t touch digital…
For Craft Recordings’ relaunch of the Original Jazz Classics (OJC) series, the mastering credits depend on the format you are spinning, as they utilized separate masters for the physical formats:
The CD and Digital Reissues: The digital remastering for the CD and hi-res streaming releases was handled by Paul Blakemore at Concord Mastering.
The 180g Vinyl LP Reissue: If you happen to look at the matching OJC vinyl release, the all-analog (AAA) lacquer cutting and mastering directly from the original tapes was done by Kevin Gray at Cohearent Audio.
(Note: If you have an older, classic 1987 Fantasy/OJC CD pressing sitting on your shelf rather than the newer Craft reissue, that original digital transfer was famously mastered by Joe Tarantino.)
this aside, it’s a masterpiece of an album and can be enjoyed no matter the format or mastering .
