Just look at the cover. I shouldn't even have to try to persuade you about this comp. As was true for a huge portion of the world by the late 1960s (Cambodia, Iran, Peru, Japan, and much of West Africa stand out in my admittedly limited experience), Ethiopia had been permeated by American jazz, r'n'b, and rock music, only to spit back out their own take on the stuff. Ethiopian musicians tended to blur the lines dividing these genres in the US, and the results are pretty fantastic.
A few of the more famous guys on here include Mahmoud Ahmed, Alèmayèhu Eshèté, and Gétatchèw Mèkurya (who fans of the Ex are probably familiar with). But the whole tracklist is stacked with funky psyched-out tunes that naturally incorporate the region's folk melodies thanks to a tendency to play traditional songs in popular styles. Musical influence from Somalia, the Arabian Peninsula, and North Africa via Sudan can be heard -- though what do I really know about that? Just give this one a listen:
