Today (Aug 9, 2008) was again streetparade in Zurich, arguably the second largest Techno party in the world (the largest seems to be the Love Parade in Dortmund), with over 800,000 participants.
This has now been happening every year since it was started by math student Marek Krynski in 1992. A huge swarm, and hugely creative. About 30 love mobiles, huge trucks as mobile dancing platforms, and hundreds of thousands of people dressed up (or down) as creatively and sexy as possible. I have always been wondering: why are people participating in such huge numbers? My answer is: emotional energy. The street party is a unique way of combining collectivism and individualism, the feeling of being part of a huge swarm, while still showing off as a unique individual. The techno rave gives a rythm to the swarm, increasing the we-feeling immensely.
