The dance music scene from around 1999 - now, had been really pretty bad, the whole underground has been taken over by posh trend clubs playin funky house, also rock music has really blown up over the last few years, what you gotta remember is: not everyone likes RnB, funkly house & pop music - theres always gonna be someone who loves techno!
I think that a lot of producers were trying to emulate the classic acid techno sound in this same time band - which is such a bad move because it soon becomes stale, i agree that lables like Cluster & superconductor, along with hydraulix and some of the SUF of late have been pushing forward a lot more, and as someone erlier said - lables like Skank are doin some wicked stuff, also glitch who bang out some ace tracks.
Iv not been into acid tech all my life - but i can tell where the lows were and i can tell its bettin a lot healthier!
