Berlin is an amazing city. This is a fact!
In Casseopeia, at the open air cinema (freiluftkino), the 1927 film Berlin: Die Sinfonie der Großstadt was shown. The venue is one of many repurposed industrial buildings in this complex in Friedrichshain; there’s an large open courtyard with a couple bars, foosball, a large tower has been outfitted as a climbing wall, a club (of course), and the outdoor theatre. Keep in mind that there’s also at least half a dozen clubs in the complex where Cassiopeia is, all in former industrial buildings.
Several years ago, a Berlin electronic music duo, called Tronthaim, created their own soundtrack to the film and began presenting it. It’s pretty f**king awesome. Here’s a clip from their website:
