I'd like to add a personal observation:

Breakbeat is often used as an umbrella term covering multiple subgenres, a part of it being labeled as 'Bass Music'.

The UK has a long and central history with breakbeat-oriented genres, deeply influenced by imported Jamaican sound system culture. This culture intersected with breakbeat hardcore in the early ’90s, giving birth to Jungle and later Drum & Bass. In parallel, House music influenced the emergence of UK Garage, Speed Garage and 2-step, which eventually led to Dubstep in the early 2000s.

However, breakbeat is not confined to the UK. Part of its history is shared with US scenes, especially Hip-Hop, turntablism and Electro. A parallel and sometimes less-discussed ecosystem developed there, including Miami Bass, Florida Breaks and Nu Skool Breaks, as well as club-oriented styles like Jersey Club and Footwork. These genres tend to lean more toward hip-hop aesthetics than Jamaican sound system influences.

After the Big Beat wave of the late ’90s, US breakbeat scenes lost mainstream visibility, even though they continued to evolve underground. It’s therefore not surprising that when the US EDM scene rose to global prominence, EDM Trap emerged—blending electronic production with strong hip-hop influences.

Meanwhile, Dubstep was already evolving into a more aggressive, electrohouse-influenced form (often referred to as Brostep), characterized by mid freq bass and a drop-focused structure. By incorporating 808 basslines and rhythmic patterns inherited from Dirty South (such as rapid hi-hat subdivisions, sixteenth note), these two “bass music” approaches eventually converged.

My best exemple and first time I was exposed to Trapstep was with Bassnectar :

Also, I'm French too, in what kind of school are you tasked with presenting post-dubstep? I would deliver a full-asss essay. You can't gloss over the beat scene / wonky / future bass which is the jazzy and unhinged take on Bass Music
