dnb and trance are the two primary genres where you'll find people into "deep" tunes who are looking to get lost in the music
really not liking the stereotype
ASC and Blame are just as dnb as Noisia and Evol Intent
but the generalisations primarily refer to the uk dnb scene (and in particular the type of dnb heads who i think are turning their gaze to dubstep). because the audience here are the ones who at the moment have most influence on the current central producers.
here, leftfield dnb is practically an even smaller scene here than dubstep! its a specialist interest, wheras thrashy or mainstream dnb (shy fx, jenna g, bingo etc) is massive business here, and they have massive, massive raves.
i said it was a generalisation, and as such it obviously doesnt apply to everyone, i personally absolutely love (some) drum and bass, and know that some of it is as deep as electronic music comes, but if we're looking at broad trends then i think theyre acceptable and carry some analytical weight when we ask why the music is changing so much, in the direction its changing
