"Behold... The Arctopus is an Instrumental Experimental Metal band from Brooklyn, New York, United States." One person writes that they are "the absolute extremes of technical and rhythmic complexity", which might be true... but its still listenable. It isn't so beyond normality that it becomes white noise. Yes, its complex, but its not like some "Speedcore" that ramps beyond 300bpm to make it a mess of... well... noise. Besides, some of the song titles suggest they are not taking themselves seriously beyond musical skill.
