Cool. Here's a really creepy cover for "Darklore Manor" by Nox Arcana. The artwork was done by Joseph Vargo, who is one of the band members. He also did some great covers for Midnight Syndicate.
Anyway, here's the Nox Arcana site.

I also like the covers for Collide; they're done by Chad Michael Ward.
