i'm a little late to chime in on all this but here goes...
just heard skull 006 and it is FANTASTIC, not just one of the best dubstep records i've heard in ages, but best singles hands down, certainly this month.
i'm not at all surprised by that turntable lab thing. they strike me a lot like the fader -- they're totally stuck in a US-centric view of the world (fuck it, NY-centric); not a lot gets in, and what does has to fit to their preconceptions. i'm sure they wouldn't get mad about their beloved baltimore club music being happy, but this early dubstep/late 2step sounds suspicious because it ain't, like, dizzee. i'm sure if you're into hip hop turntable lab is a great resource but i have little use for them; the only house they seem to rate, besides french electrohouse (yawn) is switch and dubsided and whatnot -- great stuff, but i don't see why it's so hard to make a move from that to some of the german shit. go figure.
and blackdown, what do you find so compelling about the cyrus record? i'm listening now and i don't really hear it -- but i'm also not so much an expert on the tectonic sound.
