I think tartarsky is right about the rhythms. When D&G write about rhythms and vibrations it's about bodies acting on one another in spatial relationships. D&G, in
A Thousand Plateaus, at least, de-privilege temporality which, I find, makes that part of their work not very useful for discussing the mechanics of music (since its rhythms and vibrations happen
in time). But if you're talking about how types of music operate in the cultural ecology of a city (i.e. spatially), then I think it's more useful. From what I can gather from the interview, this is more what he's talking about.
Other D&G concepts, related to nomadic "the war machine" (weight, speed vectors, catatonia), which have come up in other Kode9 interviews, seem to me better suited to discussions of musical tempos, rhythms, uses of bass, especially when comparing, say, jungle and dubstep. This idea of dubstep internalising jungle's rhythms, while slowing the tempo and shifting the emphasis from breakbeat science to bass science, seems to me to be a case of
weight being applied to the "hardcore continuum" to alter its course (slow it down, redraw its paths, deterritorialise its conventions, open up smooth spaces for the invention of new anti-orthodox
rhythmachines, etc.) to create new sonic/rhythmic equations and, therefore, new relationships between dancefloor-bodies and music/sound, as well as between people and the city. Still, I think you have to be careful with the war machine metaphor, since it comes out of this post-1968 French intellectual climate which considered the modern state be a condition of "total war" in a very literal sense (as in Virillio, and similarly in Foucault).
On a side note, I think "bass materialism" is partly a play on Georges Bataille's "base materialism." Bataille seems to have been significant to the Ccru experiment (Nick Land did a book on him).
And on the larger question of theorising music in this way (not just here, but in many discussions in various places):
I often don't totally follow the thread when reading Ccru-related stuff (and that may be part of the point sometimes), but I do appreciate the challenge and it's led me to adopt new ways of understanding and talking about music. I appreciate that people are experimenting with other ways of engaging music and its relationship to culture. It's an explicit engagement of music as theory (E.g. If dubstep really is the sound of London, what does that really mean?). Music fans are always theorising on music (how it's made, what it represents, or refers to, etc.) while pretending they're not, as if maintaining an anti-intellectual posture is essential to authentic musical experience. But all that does is deny the thought, experience and cultural connectedness that goes into each track, as if the stuff just emanates naturally from certain guys born in the right part of the right city at the right time.
Two related observations from Kodwo Eshun:
You can theorize words or style, but analyzing the groove is believed to kill bodily pleasure, to drain its essence.
...of course the way to introduce theory is to realise the music is theorising itself quite well... And there's so many concepts extant in the music that all you need to do is extract them and use them to build the machine you want to build...
