The CTM Festival (known as Club Transmediale before 2011), a music and visual arts festival in Berlin, was born out of the enrichment of a link with Berlin's electronic music clubs. Lorenz Wiegand and Nathalie Bruyère imagined the lunches for the festival over 5 years, first in the E-Werk, a discotheque located in a former electrical station near Checkpoint Charlie, then in the Club Maria am Ostbahnhof and finally in the Buker. The idea behind the design was to have the look of a building site, in particular by working with raw materials such as lighting, floorboards and BA13 panels. The Transmediale Club and these clubs are mythical places for electronic music, which developed in abandoned industrial buildings in a Berlin where there was still a lot of free space. A space of freedom and experimentation par excellence for the development of an alternative way of life, the CTM festival quickly established itself as a reference for all digital culture on an international scale.
