I got this double cd in the mail today, it was free with a subscription to a World Music magazine:
It is an anthology of a series of cds called éthiopiques, which (mostly) re-issues the lost Ethiopian music of the 60/70s. After the Emperor Haile Selassie was overthrown the jazzy music that was associated with his rule was prohibited. The series is now at 21 cds or more. Most of what is on this double cd I already have, but that's ok.
