Tomorrow evening, I will be seeing Toumani Diabate in concert here in Princeton. Diabate is a legendary Kora musician from Bamako, Mali. The Kora is basically a 21 string lute used primarily in West Africa to produce some wonderful music. Truly stunning and Diabate is one of the most prominent, if not the best.
Take a listen for yourself. I recommend it highly for working at your computer; you can drift away.
Above you can see a picture of the man himself with his kora.
