I sure did roll my eyes and make wanking gestures during the opening paragraphs. No, people aren't at a club to sit back and sip weak tea slowly whilst listening to the intricacies of a beautifully difficult piece of music. They are here to dance. And as the DJ, your job is to give them beats to dance to and keep the party going. Any number of these people may be listening to and loving that difficult, cerebral music at home, but you can't dance to that shit and they are in this place to move their asses.
