listen to it again, and then listen to the stuff coming from detroit and europe before it.
hard techno begins with this record. and no, that does not mean that other forms of music that pre-date it (industrial, some metal, avant-garde classical, etc.) did not play HUGE roles in influencing hard techno...
...but the fact is that none of those things took techno and made it considerably harder and darker than what came before it. and energy flash did.
