I haven't read all of the articles but i'm pretty sure that there is no dvd-release of those concerts. I think the files, the concerts, will be in the rockpalast archives and you can watch them until 2099.
But i found this:
From Here - 40 Jahre New Model Army
In der Nacht vom 20. auf den 21. Dezember 2020 im WDR Fernsehen.
It seems that there will be a documetary in german tv in the night of the 20th december!

OMG Cthulhu!! Another documentary on NMA!

Even if I won't understand a word of it, I don't want to miss it!

I hope they upload it, so I can manage to catch it in Canada, at some point. Please keep me loop?

Cthulhu, flodhaest and or anyone else here who'll be looking to view it, as well?
On the site it doesn't say anything about DVDs available to buy (the Ionger text at the end is a short history of the band).
There ist, however, this site: https://www.rockpalastarchiv.de/dvd.html, that lists the DVDs available. I could only find one with NMA on there (https://www.amazon.de/exec/obidos/ASIN/B000MQ3TQO?ie=UTF8&tag=rockpalastarc-21)
Maybe somebody else can find out more?
YES!!

The
Taubertal Festival 2006 DVD you found, flodhaest, certainly is of incredible interest to me! Shame it only contains just 2 of the songs in NMA's set, but I'd like as much NMA on DVD as I can possibly find... even if only a few songs are included. Too bad WDR hasn't released DVDs of their archived material, though, because their NMA stuff is all worth adding to personal collections. I wonder if NMA has any rights to make all of those performances available for DVD production, purchase, 'cause I'm surely not the only one here who'd love to own a proper, legit, copy of those past NMA gigs. Someone from the NMA front should look into working something out with WDR, to make it possible, even if just in limited run, it'd still be worth it. I sure hope so, 'cause there's gold in those performances as well. Anything NMA/JS/RSC related, is
always beyond absolute treasure, to me, for sure.

So happy both of you, Cthulhu and flodhaest posted. Your time and efforts have proved to be such a tremendous help to me. Thank you, both, so very, very much!
