I really like Black Ark a lot - funnily enough, there is a Japanese CD of it, but it's OOP and for some reason, rather expensive... more than the LP, in fact!
Scorpio was also on a Japanese CD through P-Vine, also now OOP. An excellent date that should not be missed.
I really am surprised that the Free America series did not reissue the Arthur Jones or the Noah Howard, which would have fit nicely on one disc with Uhuru na Umoja.
Will have to read this AAJ review of the Wright - I guess it's not for everybody, but it is a very fine performance.
Edit: wow, just read that. I find it interesting that people utterly slam things that they may not quite get. If it were me and I detested the music that much, I'd pass it along to another reviewer who might see something I missed. But whatever.
