From a comment left on my blog:
Toumani’s music is certainly a life changer! I went as far as actually learning to play his particular arrangements of Manding kora music on the guitar. Perhaps you’d like to take a listen: http://soundcloud.com/olly-barnett/derek-gripper-tubaka
The full album is due for release under the name “One Night on Earth: Music from the Strings of Mali” from http://www.derekgripper.com after the 12th of May. Yours, Derek Gripper (South African Guitarist)
Check out the album page on Derek Gripper's site here:
Which contains download links and some great writing about the guitar and the kora music of Malian griots.
