Here's a Soundlsides on Mali by Horst Friedrichs. It's in German but worth your while for the photographs even if you're a non German speaker.
Horst is photographer/photojournalist, who studied photography in Munich. He freelanced with Stern, The Independent and The New York Times in the nineties, and traveled to Venezuela, Pakistan, Mali and Japan. He produced a numner of books, among which is the well received Troubadours of Allah (what a glorious title!) depicting the Sufi singers (I tried to find his gallery on the Troubadours, but wasn't successful).
