The great Paco passed away over the weekend. Trained as a gnawa m'allim in Essaouira, he was a key member of Nass El Ghiwane in its heyday, bringing the sound of the guimbri/hajhouj and Gnawa influences in general into the distinctive ghiwanian mix. Here's a short obit from Libération (Morocco). Here, thanks to Tim, is an example of Paco's work with Nass El Ghiwane.
Here, at Moroccan Tape Stash, you can find, and download for free, a couple Paco cassettes and a rare casette of Nass El Ghiwane featuring both Paco and the late Boujemâa.
