The Tresor club is one of the longest running and most well known club projects for electronic music worldwide. It has become the concrete symbol of techno. The club was started 1991 by Dimitri Hegemann and Achim Kohlberger as a follow-up to the obscure "Fishlabor/ UFO" - club (that had already pioneered the sounds of Industrial and Acid in Berlin at the time). It became an instant success story, capturing the energy of a re-united city and picking up on the new musical input that had just started to become the biggest trend of the 1990s. Huge sucsess despite next-to-no publicity furthermore led to the conversion of the existing indie-recordlabel structure, and in October 1991 Tresor Records was born. 2005 the old venue had to close and parties continue to take place at exile locations until summer 2006. The new Tresor opened 2007 and celebrates 20 years history in march 2011.
