I can only wonder what astronauts must feel like or something like that when you're really in the space of silence and you are feeling and breathing in a way that you're really aware of your muscle and bone and the breath and the body and the movement and all of those things that just you take for granted in the urban landscape.

I felt like on one hand the clarity of thought was amazing, but on the other we went during Antarctic summer, so the sun didn't set the whole time we were there.

When you say what is the difference between me and my stage name the idea is that as a musician you always think of yourself as inhabiting a certain cultural space in the kind of a cultural landscape, so when I say cultural space what I mean to imply there is that you exist within certain parameters of how people think of culture.

You know you don't really need the band or the singer/songwriter in the same way, so you look at everything as part of your palette.

For me, DJ culture - with its obsession with collecting records and archiving everything - predated the "cloud" concept with primitive material like the mixtape. Now we would call it "collaborative filtering" or something technical, but the impulse is the same - gather fragments, make something new. That is how you will bypass the climate-change skeptics: render them totally obsolete.

What I wanted to try and figure out was, okay, in contemporary 21st century life the alienation between the self and the land around you or the self and even the urban landscape. You name it.

Antarctica, one of the things that was so remarkable about it was that the ice itself is a kind of pure geometry, so say, for example, if I was facing someone wearing I don't know, a Joy Division t-shirt with the mountains on it or something like that.
