Interesting article, thanks for posting. Pandemonium by Paul Woolford is siiick, nice to have an ID for it. African Forest is brilliant too. Will give that A-Plus set from Yellow a listen in a wee bit.
I reckon my feelings about this sound are similar to those of a lot of people here - whenever I listen to the Circle shows on Rinse (and I admit that this isn't on a week-in, week-out basis) I tend to quite enjoy them, but I sometimes have a hard time pinpointing exactly what is new and distinctive about what they are doing, in relation to a lot of tech-house and deep house stuff that is about internationally. The main things I could say is that in places their sound is darker and bassier than is common, and in places a bit more percussive; but only in places and not dramatically so.
But then I fully admit that I'm not a big house head, so therefore I'm not always great at making the fine distinctions between substyles that would be more apparent if you were fully immersed in the context. From the pov of someone who's been following this style of house closely for years it's possible that their take on it may respresent a new sort of slant. And of course what they're playing doesn't have to be either ultra-original or ultra-UK-centric in order to be good. But this does tend to be what people look for in the new London sounds, I guess it goes back to what you were saying about the strong drive towards cultural ownership. Anyway, def worth keeping an eye on.
