You're right, I was talking about Document (singular). Don't know anything about Documents (plural).
Document (singular) is the Scottish/Austrian label that specialises in issuing stuff like the 1920s singing preachers albums I've been buying lately, and gospel singers and bluesmen from the same period. I agree that on many of the tracks the sound is awful - but it's simply amazing that this stuff can be found in any condition whatsoever.
If, as someone said, Documents (plural) is another Membran label, well the sound on the 5 Membran issues I've got is OK for me. And the tune selection is good enough for exploring someone's work at random. But as boxes, they are a long way from what I think I want with Wilson.
So, I'm Hep
Thanks to everyone for the advice.
