both make valid points...i just want to make sure you understand, i'm not in any way making a moral statement over this about anyone, except maybe the counterfiter...
i have and would buy a boot of songs/concerts/alternative version IF it was pretty clear the artist was not about to release the stuff...i've paid an awful lot of $$, thru the years, into the pockets of various artists so that i don't feel the need to justify if, after 20 years, so-'n-so hasn't released, say, any of his early '70's shows, and there is a good boot by a fan, made for fans.
i'd rather buy from the artist, on all of it, but pretty much no one makes all this stuff available
i'm sure i'll get computer savvy enough one of these days to find a way to make copies of alt. vers. of songs and concert bits various artists haven't deemed fit for release...it doesn't worry me a whole lot: there is too, too much good music w/o worrying about the marginal stuff
its the counterfieters ripping artists and stores off that i won't deal with..and while the quality issue is definately there, as well, but nowhere near my top concern.
lift up your head...and remember what your life is !
