Omid Safi has a fine post (Sounds of Protest: Les Miserables, Gezi Park, and the Power of Music) on his blog at Religious News on the music in the recent protests in Turkey. Check it out for a nostalgic journey through protest songs since Joan Baez. Here is one of the songs he discusses, made at Gezi Park by Kardeş Türküler and called Sounds of Pots and Pans. Check out his commentary for far more. There is also a Turkish website with many tracks of protest music at http://capulcular.bandcamp.com/
