Hi there,
I just found this site a few days ago but I am into African music, both listening and playing. Check out the website called Djembefola.com. This is mainly a drum site but if you check the video section it has some really good examples mainly of west coast music.
My first instruments are bass and guitar but I have recently bought a djembe and I am about to order a gyil which is a wooden xylophone type instrument as played in North Ghana. Look up these three guys to get an idea of the amazing sound these things can produce.
Aaron Bebe Soukoura, Bernard Woma, and Kofi Ameyaw.
Also for some great African guitar demos just search for 'Soukous guitar style on youtube'.
Some good stuff. Gordon.
