Toumani Diabate
I often listen to music of Toumani Diabate (the great kora player from Mali). For me personally it has a healing effect, it is very soothing music.
I am very intrigued by this ancient tradition of the Jali (person who plays the Kora), who is a story teller. They have a role of passing on ancient tales, passing on culture and nurture the communities. They are always present at important ceremonies (birth, wedding, funerals).
