Combine the spiritual backdrop of the South African a cappella group Ladysmith Black Mambazo with the lovely top note of Emmylou Harris, and Lord, Lord, you’ve got one beautiful version of the old standard “Amazing Grace.” It’s on Ladysmith Black Mambazo’s new album “Long Walk to Freedom,” which features other nice cameos from Sarah McLachlan, Taj Mahal, and Zap Mama.

Incidentally, a whole book was written on the history and significance of “Amazing Grace.” And here’s a link to an online biography of the lyricist, John Newton.
