I just discovered recently that Bela Fleck has a new album, Throw Down Your Heart. In 2005 he went to various regions of Africa to study and discover the origins of the Banjo, which, it turns out, is an African instrument by birth. While there he discovered some amazing musicians and played with them and recorded with them and came up with some very interesting music. Really amazing stuff.
Also, he is touring with Toumani Diabate with his Kora June 11-19 and also August 3-8. The tour doesn't come close enough to me for me to be able to see it, but man that would be something to see... and hear.
