For the moment, this is just a place maker, and a tribute. I really like the Alexandrian music group Eskenderella. (And think about it, what a clever name!)
This is their song, Rag'een (returning), their tribute to the Egyptian revolution, and their first video. It is far better than most of the songs of and for the revolution that I have come across. It is certainly far superior to and has way more integrity than any of the martyr pop critically discussed by Dan Gilman. (See my earlier post here.)
Hopefully, in future, I will learn more. In the meantime, here's the one bio I've been able to find on the web. They are known for doing material by Sayyid Darwish, Shaykh Imam, and Ziad Rahbani, as well as original numbers.
