I composed The Darkness Behind the Light last year and is meant to be an etude for a late-beginner/early-intermediate guitar student. The piece consists of a melody (top voice) and bass voice (bottom) with an occasional inner voice.
While composing this I imagined a creepy scene (Halloween-ish) with a dark doorway full of mystery.
I hope you enjoy this teaching video. You can find other videos like this at my guitar school found at my website.
