“Run On,” often known as “God’s Gonna Cut You Down,” is an old American folk traditional about how you can’t escape God’s wrath. The Golden Gate Quartet released the first known version in 1946. Elvis Presley, Odetta, Johnny Cash, and many others have recorded their own version of “Run On,” and Moby famously sampled it for a song from his massively successful Play album. Now, PJ Harvey has also taken on “Run On,” and its apocalyptic emotion seems like it was built for her.
