Back in 2008 I wrote an 8 bar loop for a collaboration that never happened. A friend of mine asked to use it for a version of his own (which can be found on my youtube under the name One Bearded Collab), but I've long wanted to make a version that's entirely my own. I did it just now.
The Bell Crow is a figure from a game I'm getting soon called The Edge: Dawnfall, here's a bit of a description of him:
"There isn’t however any kind of blood that could protect you from Lords of Terror. They are the most ancient and powerful inhabitants of Darkness. One of them is known as Bell Crow. It commands hordes of smaller Nightmares that disguise themselves as crows and fly only after dusk. The only thing that distinguish them from other crows are bloody red eyes. Wherever they show, they are an omen of horrors to come. Although bell crow lost his eyes he can see through his countless minions. He also has many servants in demon’s terror caste who must answer his every call."
I think this song would qualify as a way to summon him.
