Just as a matter of interest (to me at least), why has Dogon A.D. never had a proper, official release?
I assume that it has to do with complications in obtaining rights from the Hemphill estate. I know that Tim Berne was planning to release it on his label, but gave up.
Berne had it up as a download for a while on his site. It is a classic! Maybe the fact Freedom issued it at one point complicated the rights.
