Bass is the center of gravity, not a restriction. Groove can arrive through funk, hip-hop, house, breakbeats, or a rock record cut into a new shape.
The connective tissue is pacing: when to build, when to breathe, when to let a vocal reset the room, and when to push the strange part all the way forward.
The best transition is not always the cleanest one. Sometimes it is the moment two records reveal that they had been related the whole time.
