Hobbits beware, because Saruman is back with something more powerful and destructive than the One Ring, and that is heavy death metal. Christopher Lee, the 92-year-old actor who played the corrupt wizard in Peter Jackson’s Lord of the Rings trilogy, has released another heavy metal Christmas music single, based on “Darkest Carols, Faithful Sing.” This is the third consecutive year that Lee has released heavy metal holiday music, though he’s been at it since the mid-2000s.
