You don't have to be trained in music to create sounds and to produce and release music. That's what we were saying back in 73-74. And that's the way the world is now - and all the tools of creation, production and dissemination are there in everybody's bedrooms, front rooms and studios.

Some of it was shot in Berlin, but a lot of it was filmed in Hamburg, along the Reeperbahn in Hamburg in the famous red light district. Kino is obviously German and "film" and "cinema" and we were always cinematic in our thinking.

We were responding to a period in the 70s when we started that it was very much you cannot be involved in music unless you studied to do music.

We've always been observant of things, and I think Crackdown was very much like that and the film interpretation was that journalistic view of that situation.

I think that's the fascinating thing that exists now. This contrasts with a celebrity art and celebrity music culture.

We were working in entertainment, in the music industry, with popular music, it was important, but it was something that we also felt was a responsibility.

I don't think it had a name when we started. If punk has any roots, Dada is part of it. And we saw ourselves as part of a kind of Dada tradition.
