At 146 the kick doesn't swing so much as bore, a straight unsentimental pulse with metal filings in the hats. Everything sits in A-flat minor and stays there; the harmonic movement is a slow smear rather than a chord change, filters opening a quarter-turn at a time while the low end keeps its shoulder against the door.
Energy pinned at ten, but it's a claustrophobic sort of intensity — the walls come in rather than the ceiling going up. Drop it early in a long, dark set, or as the hinge into the final hour; it thins a floor of anyone who came for hooks and keeps the ones who came for pressure.
