Great music can come from anywhere around the globe. And there has always been a music business. It just wasn't recorded, nor was it centered in New York, London, Los Angeles or Nashville but rather St Petersburg, Vienna, Berlin, Milan and Paris.
Ironically, even the fashion in New York or Paris or Milan or whatever, or music in Berlin, or art in, I don't know, Madrid - all these scenes come and go. Everything leads back to Hollywood.
The best city for fashion is Tokyo. You see styles there you won't see in London, Paris, Milan or New York. I also like the fashion scene in Los Angeles - it has a unique look.
Los Angeles and New York are the big centers of the music industry worldwide so of course it can be hard for newcomers who don't know what to expect from the music business.
The climate suits me, and London has the greatest serious music that you can hear any day of the week in the world - you think it's going to be Vienna or Paris or somewhere, but if you go to Vienna or Paris and say, 'Let's hear some good music', there isn't any.
Los Angeles has always been overlooked as far as jazz, and just high-level music in general. But, like, my dad's a musician, so I've grown up around so many brilliant musicians that nobody outside Los Angeles knows about.
One of the problems with any kind of talking about the media landscape is that we've just been through an unusually stable period in which, for fifty years, English language media was centered in three cities - London, New York, and Los Angeles - around a very stable group of people working in a relatively stable set of media.
I'm an adaptable nomad. I love Paris, I've been living in Los Angeles and New York since 1990. I love London, too. My roots are inside of me.
... coming to a place like Nashville, which is just music music music, it's always been such an influence on me. And there are so many interesting songwriters out there, and it's such a crazy business and so many people are trying to do it, and it's all right there in Nashville.
I love London, even though the weather's not great. I've travelled the world and I've lived in Paris, Germany, Los Angeles and New York but I love the parks, the theatre and the Britishness and the way that all these communities have integrated.
People constantly make the mistake of comparing London with New York, Milan and Paris and that's not what it's about. London has its own fashion identity. You come here to find the next Alexander McQueen or John Galliano.
Los Angeles is one of the four cultural capitals of the world, but we don't attract as many cultural tourists as New York, London or Paris. I want to change that.
The thing about New York is you can leave your house without a plan and find the day. You can't do that in Los Angeles. You need to get in your car, all this, you can't just drive around like a lunatic. In New York, you can literally walk outside, and wind up anywhere.
When its 100 degrees in New York, it's 72 in Los Angeles. When its 30 degrees in New York, in Los Angeles it's still 72. However, there are 6 million interesting people in New York, and only 72 in Los Angeles.
We've got the prettiest girls in the world here in Los Angeles and there's a great music scene. And I learned what I learned about cinema here in Los Angeles so it's always been really important to me as a city to live in and I love making movies about it.
London has always been open to trade, people, ideas. We have to keep that. I want to compete not just with New York, Paris, Berlin... the ten fastest growing cities in the world are in China. How do we compete with them? We have to attract investment and we have to compete on skills.
I love New York - maybe more than Los Angeles or London. I think I'm happiest in New York.
