For as long as I've been listening to the Zappology podcasts, which are available at the Internet Archive, they're still something of a mystery. Their "About" page doesn't provide any background and a web search doesn't turn up any more information about the who, what and where of the thing.
For lack of a better term, I call them podcasts, although they're just collections of music - without commentary - with each lasting about 90 to 120 minutes. They cover a very wide range of musical categories, with nearly 1,100 programs listed, in all. For purposes of this post, of course, we'll narrow it to the ones that deal with African music. There are more than 50 of these and they cover much of the continent. The most popular is a collection of so-called "desert blues" music.
I've tried and failed to retrieve a direct link to the list of African programs. But if you click here and click the "African" box in the left-hand column, you're there.
Here's an unrelated video of Ali Farka Touré & Toumani Diabaté - just for the fun of it.
