I felt that there's an obligation when writing a piece about an urban expressway made in the 50s to acknowledge the context, and Robert Moses is sort of an iconic figure in New York, and he influenced the shape of the city more than anyone else before or after him. He was one of the most powerful and influential civic architects in the world, because of how much he transformed the city. He built multiple bridges and highways and parks and recreational spaces, beaches - in the course of a few decades, he completely changed the city

The World's Fair was the precursor to theme parks like Disneyworld, and the really sort of cheap, superficial promotional architecture that you see everywhere in the US. I think there's a danger when you start creating a civilisation that isn't meant to last.

It's nice for me to have a ballet as a kind of platform for creativity, because unlike modern dance or contemporary dance or downtown dance, ballet is formalized, and there's something orthodox about it that I like. I like that there's less emphasis on subversion and innovation. I actually think that my musical vernacular or my musical voice is also less inclined toward innovation and subversion. I think I'm a traditionalist.

I'm no longer beholden to the sacredness of the recorded song as some kind of ultimate standard by which every performance of the song is measured. I like to diversify, that there are multiple versions of every song. And the songs incorporate a lot of improvisation, and an element of chance, and I think that's exciting. There's no one true formulation of a song, they have various manifestations depending on the space we're in. I like that.

I was feeling privileged and self-conscious about my life as a musician, which feels self-absorbed. I can't help it, I am a musician. This is what I do.

The round-up is an aggressive tradition. I'm trying to objectively be a steward of the tradition and what it means in its choreography.

There's nothing cutting edge about what I'm trying to do. I'm not creating a new sound. I'm not like Bjork, who's an alien from another world. I'm of the earth. You could extract any measure of music out of anything I've ever done and you could find its affiliations in music history.
