There's something rather wonderful about a centuries old fortress being reclaimed each September as a proper rave destination, complete with strobes strung through the grass and natural wine dispensed from actual bombproof bunkers. Making Time ∞ sounds like it's cracked the code that so many dance festivals chase but never quite catch: the ability to feel genuinely subversive and historically surreal whilst still delivering the goods on the dancefloor. For Cledvibes Radio listeners who've grown tired of the corporate festival circuit, this East Coast operation seems to understand that the best raves happen when you're dancing on borrowed history, with aeroplane noise as your overhead lighting rig.
