Is that a bad thing? Surely one of the things that gives the continuum its vitality is how quickly things move forward. A producer makes some radically different music with a few different influences, someone else does the same based on that producer, etc etc etc exponential growth to the extent that the music rapidly becomes unrecognisable to what came before it. I mean, the sort of UKG sounds I guess you're talking about was what was going on about 6 years ago (at least!) - couldn't you level exactly this critcism at no u turn with respect to 1992 hardcore? 'Ah mate, all this stuff is so fast now, and it's so dark! It sounds nothing like old Moving Shadow.' Completely different music with only the most tentative links to each other - and that's only 4 years apart, maybe even three. Is it really such a surprise that dubstep of 2007 doesn't sound much like Groove Chronicles anymore? And more to the point, would you really want it to?
However, having said all that, I would rather listen to almost any big name DJ out there other than Hatcha, and I've felt like that for a good long time
yes it is a bad thing as the music was good and now on the whole isn't, it's very boring.
no u turn also wasn't the only choice at the time it came out, whilst stiff halfstep wobblers pretty much are.
no ones asking for groove chronicles they're just asking for better music and whilst groove chronicles is better music people want a continuum and development rather than a flattening out.
