Great CD for anyone interested to the Sacred Songs of the Lakota Sioux. When I listen to it now, I put myself in a state of meditation and here I am with them, as if I was participating in their ceremonies. There is something magical happens in me. I feel deep in my being, peace and serenity. I also bought the grammar Slim Batteux: I speak Sioux / Lakrota. Authentic songs. A breath of fresh air!
