Raver party at Warschauer Strasse

I stumbled across one of these illegal raver parties near Warschauer Strasse in Berlin. These parties are more or less spontaneously organised by a group of DJs who tell their patrons by sms about the location. Usually these parties last for a few hours before the police come and disband them (only for the organisers to regroup at another ‘secret’ location a few hours later… again you need to be in the ‘inner’ circle to know about the new location)… Seems there is still some of the independent/anarchic spirit in Berlin…
