Sheesh, the "owner" doesn't own anything really, does he?
I'm not one of the pirates or anything, but bootlegs belong to the musician or else to everyone or whatever do I know. And demanding (sorry if I misunderstand your first sentence, Mr. Marcello!) a high price (i.e. wanting to make some money out of it) is all the more sorry-assed, I'm afraid to say, even if this is a treasure. I say let's hand it to the Library of Congress or some such institution, at least it should hopefully be conserved then!
Anyway, on topic: this 4LP box looks pretty tempting to me, indeed! Has anyone gotten any of the recent Mosaic vinyls, how is quality?
