“The idea of uncontrolled, wild dancing as something dangerous stays with us: the club must be licensed for entertainment; the rave strictly policed. The idea of people enjoying themselves, whirling like banshees out of control is deeply unsettling to authority. Uncontrolled passion must be restrained. Yet in the not-so-distant past, hundreds of thousands of people took part in frenzied outdoor orgies and wild displays of dancing that lasted for weeks. From as early as the eighth century and as late as the 17th, these dance manias spread across Europe.” The Guardian (London)
