I thinks it's about the origins of heavy metal and bringing it to the US. Led Zeppelin, Black Sabbath and Judas Priest are all from the Birmingham area in West Midlands of England which was/is called the Black Country. It was called the black country because of "the smoke, the dirt, the grim" from the coal mines, foundries and steel mills. , These three bands are the godfathers of metal and they brought it across the sea to America.
