It bears more than a nodding reference to 'that' track from the Wall, which to me doesn't speak of 'That Day on Calvary' at all which I see as the resolution of the story, this piece may have worked better as the journey to the crucifixion with all the fear, pain and cruelty surrounding that.
Aside from the musical caricature of an old Pink Floyd tune there only seems to be a relentless solo over the top of it. The solo might be cool but I think more something more structural to pin the solo to and depict that part of the story may be required if indeed it is meant to be setting some kind of scene.
Just as a guitar jam though it works a treat.
