There’s a great little video here about the re-mastering process for this set with Doug Benson and David Sager: https://www.mosaicrecords.com/jazz-gazette-news/
There’s also a promising new release of a subset of this material from Alay: https://www.alay.ch/album/from-fargo-live-1940
The sound restoration & mastering by Michael Brändli is some next level wizardry.

Ugh, this shipping is wild. Tracking tells me my set has been from Secaucus USA to Sydney Australia and now back to Secaucus. I’m in Melbourne. I don’t know what to expect anymore.
I’ve said this before, but I’d really really really prefer they just take my money when I order it. Then I have control over when they take money out of my account, and what the exchange rate is, AND they get the bonus of having the money up front to keep things moving.
