This post is about goosebumps. This is what I get from visiting http://nikiibu.wordpress.com/, a site dedicated entirely to Salia Koroma, a Mende accordionist from Sierra Leone.
I can only bow to so much thoroughness.
I have nothing to add to this site except this cassette which I copied from a friend who visited Sierra Leone in the 1980s. The cassette does not have a title, only "Salia Koroma # 40".
As an illustration of nikiibu's thoroughness I add a video borrowed from his/her site. For others, and for more of and about Salia Koroma I humbly refer you to http://nikiibu.wordpress.com/.
EDIT June 11, 2013: The link has been renewed.
