Bass house grafts the heavy, modulated low-end of UK bass and dubstep onto the four-on-the-floor frame of house. The style took shape in the mid-2010s on labels like Confession, Night Bass, and Insomniac, drawing on the bass-music traditions of UK garage and grime as much as house. Tracks usually sit at 124–130 BPM and pivot around aggressive, vocal-chopped drops; the energy is closer to festival main stage than club. Producers like Jauz, AC Slater, and Chris Lake helped consolidate the sound, and the Dirtybird family has pushed a more playful, percussive variant. Bass house bridges the audience between house and harder bass-music subgenres, and is a regular fixture of US festival lineups.
