This is a stonking classic, Richie Hawtin's been playing this for years, released on his own imprint over 10 years after its original release, he plays this all the time, I love it. Both mixes are good but the A side is the best, minimal stuff with massive drum rolls, leading to the mad siren sound which makes this track, with its onslought of percussion, just rock the house. When the high hats and bass hit you in the face this nothing short of pure madness.
