The 1970 Black Sabbath song "Iron Man" is a heavy metal classic, no pun intended. Or maybe it was intended. Anyway, you can't get any further from the popular concept of heavy metal than the angelic music of the harp. So of course, Camille and Kennerly Kitt, known as The Harp Twins, had to play the song on harps.
In case you're wondering about the fascinating backdrop, this was recorded at the Sanfilippo Estate in Barrington, Illinois. See more videos from the Harp Twins. -via Digg
