I think that’s gas tbh. What if they hadn’t abandoned and had just died in a plane crash together on the way to some rave or something, would that still kill things off? Nah.
This is a new thought, for me, so bare with me a moment. But I don’t think it’s even correct to say the scene died, it started out as a bunch of nobodies playing tunes to their mates in a couple of empty clubs, and there’s still plenty of that going on today. I think the worst thing for it was people getting too caught up in “the scene” and other people’s business and not just focusing on their own production. IIRC, that’s exactly why Loefah at least left. I remember reading an interview in which he said that he’d begun to load up his DAW and try to make dubstep, and not just make tunes to impress his mates. And that’s fucking shit.
