"I think that DJ and dubplate culture is the biggest thing to blame for the dip in quality control. DJs are only playing records that get an obvious response. So you may play a deep house set that people will sway and bob around to and it will change their lives - or you may hear an absolute full-on attack of warped noises that'll make people scream and bang their heads against the wall and then they'll never look back on it. Basically they wanted a release at that point and this is music that will have no effect further than that. If you're a dj it looks like they loved it because they're going mad, but that doesn't mean the people are buying the music. They'd rather spend their money on good drugs and clothes and then just go wild."
Rupert Parkes, aka Photek, interviewed in Overload magazine, late 2000. Of course he's talking about the d'n'b scene, but perhaps this line of thought could be applied to dubstep today.
