with a strong connection to the ruhr area in the name (beton = concrete), I wanted to play with the regions contrasts for the logo. while being unarguably ugly, grey and encased in concrete, there is a sort of magic about the area and its people. ruhrpottromantik is hard to explain, if you get it you get it. think of a flower growing out of concrete or watching the sun set over an abandoned industrial site.
this contrast of harsh and fragile is reflected in the choice of typography for the logo. having a clean and thin sans-serif for the syllable “TON” (=sound) surrounded by a very bold typeface resembling blocks of buildings, while at the same time looking futuristic and therefor making the connection to cyberspace, where the radio is happening.
