I don't know the answer, Ö, but I can't help feeling very sad, this recording is such an important part of history, it needed to be hailed as a legitimate, official (by JPInc) posthumous Jaco release (maybe it is?), with the proper cover, and reviews. Of all the recordings that have surfaced, this particular one was something Jaco owned and left his four children, not some random tape to be butchered, it was real property that belonged solely to the 4 heirs, though I cannot say what the circumstances are, there is just too little info about it. Must be so great to listen to, truly legendary.
