I used to be massively into breaks from about 2001-2006. My favourite breaks DJs were Adam Freeland, Lee Coombs, and Hybrid (although all of those used to play other styles as well as breaks).
One of my best mates was a breaks DJ, and I spent many hours round his house listening to him DJ, so I really had my finger on the pulse for a while. But he got into 'heavy breaks' around 2005 (the likes of The Autobots and The Breakfastaz), and I really wasn't into them at all.
- you may have even heard of a night called 'Fuse' that used to run in Manchester (maybe it still does?), which was at the heart of the heavy breaks scene. I went there once (around 2005/2006), and I will admit the music had a lot of energy.............but y'know............I like the occasional blissed-out moment, rather than just constant fast breakbeats and relentless basslines (some of the DJs that night were also scratching on top of all this). I actually remember thinking that the music there sounded like slowed-down drum n bass (it was significantly faster than most breaks - could easily have been 150bpm).
The last 'breaks' artist I got into in a big way was Evil Nine (and a lot of their stuff actually has a 4/4 beat). But that was 5-6 years ago.
