I disagree. A major problem is that rap's canon was written by New York and Los Angeles because those are the two major media access points in America, meanwhile America at large is... well insanely big.
This is the antithesis of Luka's theorems where constantly all of England is actually defined by London, which is actually defined by East London, which is further minimized focused into (effervescent gesture). America is too vast and things happen all the time where nobody notices. Inventions, innovations, and nobody cares. Much like the techno debates elsewhere on this forum, think of how much happened in these small pocket cities of America and how much was constantly being bounced back and forth along through the nation. Detroit's techno neighboring Chicago house, battling NYC's hip-hop, Miami's Bass (not to mention Atlanta's Bass) and LA's Electro/boogie. That happens on a much smaller and more easily disregarded scale in the UK because it's a significantly smaller population and smaller span of land which means the immediacy is so much harder, even with modern technology. Nothing can actually duplicate the ease of being in a physical space. So much of this country lacks the claustrophobia but is too schizophrenic for any display of Subjective Representation. Too many names, too many cities, too many faces, too many eyes.
Hip-Hop went a far way without the sampling all over the country and then eventually sampling went the way of the dodo. It's now a vanity flourish.
It's why Jungle is a dead end genre. Not because it can't innovate further upon itself (it can) but it NEEDS the sampled drum. Whenever these producers try to sculpt these fake tin robot drum sounds to avoid chopping 'the same old same old breaks' they just reveal skeleton tunes. Woebot was right to argue that Hip-Hop is the real lifeblood of jungle, but he didn't know what he was doing because he falls for the British novelty of mistaking Public Enemy as an exemplary of rap instead of being an anomaly.
