I have been listening to the new album from Tinariwen like crazy. I have no idea what they are singing about but the same goes for when I listen to Radiohead and Pearl Jam. The last album "Emmaar" was great but this one raises the bar. If you have not checked them out this is a great place to start. Amassakoul is another album of theirs that is fantastic if you become a fan. I highly recommend listening to this album with headphones on to hear all the intricate layers they stack into their songs. Kurt Vile does some electric guitar tracks on this album as well which is a bonus.
