A certain appeal
Your juxtaposition of melodic chimes and frenetic, almost random rock pounding (as referenced in the title) is quite unlike anything I have heard before. Its uniqueness gives it its appeal, but I have to say that it gets repetitive. Perhaps you could have explored a softer sound somewhere around the middle or near the end to give the entire song more contrast. It could have made the louder parts more interesting and something that listeners could look forward to.
Just some suggestions. Great idea, good utilization.
