Just discovered, albeit ironically via itunes, the Touareg group Tinariwen. From Mali, these musicians are all former Touareg rebels who in the 80's lived in refugee and military training camps in Algeria & Libya and in the 90's, when peace was established, put down their guns and picked up guitars...lucky for us.
I'm planning on looking for their CD's here in Djazair, but might not find them as I read somewhere that their lyrics have been banned due to "political content." Fortunately I'll be travelling soon and will hopefully find them in France or the US.
Their new album "Aman Iman: Water Is Life" will be released in March, and I for one, can't wait. It was recorded in Mali and was produced by British blues guitarist Justin Adams, whose 2002 album "Desert Road" is also worth checking out.
