It may be unfinished, but the riffery at the beginning is reminiscent of a cross between Black Sabbath and Pantera, which is to say it's heavy as hell. You break the death march with a lyrical stab of lead guitar, then finish with a great little solo that seems to use a traditional kind of scale. Overall, I'd say that this and Pensive are your best submissions.
Please contact me if you would like to use this in a project. We can discuss the details.
