All of the artists that I've worked with have an incredible work ethic. And Madonna has the best work ethic of them all. I've learned a lot from being around her.

I've worked with everyone from Ice Cube to Snoop Dogg ... right across to working with pop stars like Justin Timberlake. Why those artists came to me is because they wanted my sound.

Shanghai set out to take over from Hong Kong and I think it's done that. It's got the most amazing futuristic skyline which rivals and even betters Tokyo.

I never thought electronic music would get as popular in America as it has. When I first came to Vegas in 2009 for my residency - we were they only people playing electronic music at that time.

There is a definite Chinese pop sound developing, but I was shocked at how influenced it is by American music.

When I started DJ'ing, it was no big thing. There was no money in DJ'ing, and you did it purely for the love of playing music.

It's good to see that America has a hub for electronic music in Vegas, like Europe has with Ibiza.
