I really cannot recommend enough this recent post by John Doran on The Guardian's Playlist series. He covers a lot of interesting material, but I was most moved by the mahraganat mixtape and, much more revelatory, the black metal from Saudi group Al-Namrood.
First of all, Egyptian mahraganat artists Vigo, Sadat, Knka and Diesel were in London in January and they recorded a 48 minute set, with Kode9 lurking. They collaborated with Faze Miyake, Kode9, and Artwork in producing it. (You can not only view but you can also download the set.)
And then there is the mixtape produced in Cairo with the same artists with the collaboration of Mumdance. You can read about it, and download it here, and this is the set list:

And second, there is that Saudi black metal band. Black metal: not my cup of tea. But these guys (who record in total secret) mix in oud and qanun and derbouka and ney with the metal guitar and bass and drum, and the results are pretty amazing. So go read about them and check out the Youtube vid posted by The Guardian, but also check out this one:
And then go buy some of their music on iTunes or emusic or whatever.
There is much more discussed here by Danon, but these were my faves.
