Cool! This will be fun to hear.
I think we're lucky that so many archival recordings from Europe are being made available; for example, the NDR series, the OTRF stuff, the recordings from Onkel Pös Carnegie Hall, and now this Dutch Jazz in Paradiso series. There are examples of archival releases from the U.S. -- like the Left Bank Jazz Society, the Penthouse, or the Keystone Korner -- but it seems like there's SO MUCH more from European sources. I suppose this is because these recordings were often made for radio broadcast in Europe. In any case, I'm glad that these sorts of thing are being released.
