One of my all time fave's by techno Goliath Richie Hawtin. It has the kind of sound he abbandoned what now seems like decades ago, in favor of state of the art minimal electronic music, but this one just has that raw and unpolished old school madness written all over it. It has a long and building intro with a relentlessly pulsating, window shattering kick just hitting you until a few seconds after the 03:30 mark when you're thrown in a steam pit with a repetitive acid siren. What you're left for the next seven minutes is a never ending plethora of minimalistc banging percussion with a constant yet simple drive with an acid riff drilling holes in your cerebrum with no more sense of time and place with... Whatever... Call It What You Want!
