The tree basically called on all collectors and they collated the results. I don't know of any of it that wasn't already a known quantity back in the days of cassettes and goodwill.
A lot of this stuff, including most of the 60s tour with Trane, has been "available" for a while, long before the internet. I say "available" because once upon a time, you had to cultivate relationships with individuals just to get a foot in the door of maybe asking somebody for something...and hardcore people would demand material in return. Beginners not allowed.
Dime and stuff like that killed most (but not all!) of that, and maybe not for the better, but shit like Paris 60 with trane...before it was made official (or even semi-official, like the Trema) ..not everybody appreciates that, ok? To them, it's just another gig. And it's not just another gig.
For too long material like this has been cheapened just like any other common whore, there it is, pay your bit of random pocket money, use it and then move on. Or even worse, here it is, take all you want and then come get some more. Something like that (and others like it) deserve more than that. If people don't love it, they shouldn't come after it, and they for damn sure shouldn't have it as part of some random act of gluttony.
If that's "elitist" or something, so be it. I stand firm on it.
