I'm surprised that there was no mention of Detroit here. As far as electronic music is concerned, especially stripped-down techno, the two cities have numerous connections since the early 90's. They are almost sister cities in the evolution of techno. In fact, a couple of our best known electronic musicians have lived in Berlin for a time. The exchange of DJs between the cities has been ongoing for decades. I've never been to Berlin, but I've heard a number of comparisons between Detroit and Berlin that extend beyond music. I've actually never heard the Austin comparison. I saw Kraftwerk here in Detroit several years ago, they got a very energetic reception.
That's a great point, and one that makes a lot more sense. Underground Resistance has always been a popular label in Berlin techno circles, as well as around Europe. I know of a lot of local producers who will emphasize Detroit in their US tour schedules, or go play festival one offs.
