npr.org: "Her latest CD, Volta, is a high-energy, tribal romp across cultures, with rhythms from Africa, horns from Iceland and strings from China. Björk performed live on NPR.org, in a full concert from New York's United Palace.
Volta is more political and international than her previous albums, though not overtly. It's a sonic essay on the state of the world, particularly war and the human impact on the environment, both of which can be heard in the opening track and first single, "Earth Intruders."
Though Volta is driven by strong, polyrhythmic beats, Björk says it was the last thing she thought of for the album." Download here
