I know next to nothing about Massnawa, other than that they are a Moroccan group, in the ballpark of similar Moroccans Lemchaheb, Jil Jilala, and Nass El Ghiwane.
I don't even know what year this cassette is from; no one has yet added this album to Massnawa's Discogs page.
All I can tell you is that it is one of the most inventive Moroccan albums I've ever heard and I doubt you'll feel any different.
