While I've been poking around the internetz looking for stuff on the Tuareg rebellion, I came across Tinariwen. Tinariwen are a blues band from the Sahara. Here's a documentary on them, with video of them playing as well as interviews with assorted members and other random people. 18 minutes long but very interesting. I found it via Ghasbouba.
Here's another video of them performing with Carlos Santana.
