It's not a stupid idea for an article and is, in fact, true. the uncut article wasn't too in-depth but made sense. while i'm sure that there is someone making 666 bpm satanic shred metal/hi-energy/disco gabber fusions in putney, they won't be very popular and won't make much of a dent in mainstream of tastes, so throwing up examples of minority-interest scenes in contrary areas doesn't really make too much of a hole in the argument. The fact is that London and Bristol have more sizeable Jamaican communities than most other places in the country, therefore reggae has exerted a bigger influence on dance music, slowing the pace, at least at bassline level (c.f. jungle), and placing emphasis of bass pressure (c.f abso-bloody-lutely everything) in a distinctly jamaican soundsystem-influenced way. also, let's not discount the fact that they're two of the best places in britain to buy decent weed, too. in scottish urban areas, not many jamaicans, not much reggae, lots of white kids from economically challenged former industrial areas into stimulant drugs and booze = mental fast techno, much as it does in holland. it is general, but it works on the whole.
