Been listening NWW Flawed Existence box set on VOD. 4 LP's, 10", 5",... in neat red velvet like box. Some early tapes here, as well as compilation tracks and unreleased ones. Main thing to write about this, is that if someone has this on shelves, I'd recommend to check out the condition of LP's.
Same with the VOD's Psychnic TV box set, with the industrial-strength glue used in attaching velvet to LP cardboard, some surprise revealed later on. This actually reacts with the vinyl itself, causing vinyls to "melt". I was unlucky enough to have storage Psyhic TV LP's between gatefold covers and therefore the glue melted one side of each LP in this 4xLP set..... You can still play them, but there is LOUD veil of hiss on top of everything and vinyl turns to matte-grey'ish. It doesn't matter that the LP's were inside polylined innersleeves!
With NWW box, all the LP's were luckily outside covers, but also not in physical touch with any of the velvet. However, the 10" with unreleased NWW recording was inside the cover and similarly "melted". Worthless to listen anymore.
Now that years have passed, I'd recommend to check what has happened to your NWW (or PTV) boxes if you have them. It would be quite curious to see if some dealers have stashed "mint" limited membership boxes what are now ruined unlistenable......................
