Each Nox Arcana album is built around a specific concept and they are all deliciously creepy. Now, full confession here - I loathe horror films. So how and why this spooky music makes my day is utterly beyond me. How it translates into anything remotely science fiction is also beyond me. Halo and Myst - even Pendulum - those I get. Not this stuff. Still. I love it.
Have a gander at a bit of Pendulum:
My current soundtrack? Earplugs. The heroine for book three of my scifi series is deaf.
