yes the hard techno/schranz scene here is pityful. the dj's you mention only play the very commercial and cheesy edge of the sound. tbh i cringe when i hear them play it as to me if you're gonna play hard techno you need to do it properly lol. and as for an underground movement in the uk, well there are people who absolutely love it and try to do their own thing but tbh you really have to look abroad for the real deal. if you wanna here full sets of this stuff search for dj's like sven wittekind or pet duo. there's some nice mixes posts in our filez section you should d/l and check. there a party mix of me at a hydraulix party that i was quite pleased with - it gets very hard at the end. ask me anything you like about the particular section of the mix you like the most and i'll try to give you some more direction to the stuff you want ;)
