I don't believe that someone will share this. I've asked for unreleased Fugitive Brothers remixes that were shared but now link is dead.
I understand why such recordings as Face It Alone not shared yet. Because demos like FIA have collection value.
But already shared mixes DOESN'T have any value at all, especially officially released, like BASIC Promo. Collection value may have promo CD itself, NOT recordings from this CD.
This situation reminds me about Stanford experiment. Give to man any power, even rare tracks, and...
I don't think MP3's/FLAC's are so precious... it's cool to have of course, so if you got something special I think you should share it with us here on this forum - It's the right place to do it. Probably none of your real friends care anyway...
