Charley, The CD's I worked on were put out by a group of ex-pats here in D.C. I am not sure if all of them were released, but one I know came out about 10 years ago, it's called "Chewata" I think and traces 150 years of Ethiopian history through music and stories. Many musicians cam in to sing and play on it from all over the world, included the former professor of traditional music at the University of Addis Ababa. The producer was a chap named Abrahim Wolde who I understand was a TV star over there for a while, very interesting fellow. He told me that Haile Selase's grandaughter wrote to thank him for doing the project. I may still have a promo copy lying around the studio somewhere so pm me if you are interested.
I lost touch with them shortly after they completed the recordings as they had some problems paying the final bill, so I got stiffed but am a better person for having known them and their music.
