I found some great world music on NPR today. Rachid Taha is a leading Rai musician. He's a second generation Algerian immigrant to France and is now one of the most sought after artisits in France. He's nominated by the BBC for the World Music Awards too. I liked Ya Rayah and Mamachi tracks in particular. Ya Rayah is a widely popular Algerian song that vaguely means "the feeling of homecoming is always present among first generation immigrants." Wonder how this song is perceived after the recent French riots. There is a more recent track called 'Tekitoi', that sounds like a Bollywood remix. You should give a try. (All tracks available on iTunes Music Store)
I got one other track called "My Comfort Remains" by Nusrat Fateh Ali Khan and Michael Brook. I think I am falling in love with Sufi music.
