I have written most of my melodies walking and I feel it is definitely one of the most helpful ways of sewing all of the different things in your life together and seeing the whole picture.

I'm self-sufficient. I spend a lot of time on my own and I shut off quite easily. When I communicate, I communicate 900 per cent, then I shut off, which scares people sometimes.

I'm not sure if it's because I'm older and I'm thinking about family more, but I'm trying to set up this thing where I can play in one city for a month, and then write music for a couple months, then play in another city for a month, write music for a month. Just so it's not these two schizophrenic, Jekyll and Hyde kind of things; you don't have to be this monster. You get inspired and you can go write one song from that, and then you go back and play a few shows. If I could've done that in the 90s, I would have.

[As a kid] I felt it was really weird that music schools behaved like a conveyor belt to make performers for those symphony orchestras. If you were really good and practiced your violin for a few hours a day for ten years you might be invited to this VIP elite club. For me music was not about that. It is about freedom and expression and individuality and impulsiveness and spontaneity. It wasn't so Apollonian; it was more Dionysian.

There is this stereotype of Icelanders all believing in spirits, and I've played up to that a bit in interviews.

I have nothing against Kanye West. Help me with this - I'm not dissing him - this is about how people talk about him. With the last album he did, he got all the best beatmakers on the planet at the time to make beats for him. A lot of the time, he wasn't even there. Yet no one would question his authorship for a second.

It seems that most the world is driven by the eye, right? They design cities to look great but they always sound horrible ... They design telephones to look great, but they sound horrible. I think it was about time that the other senses were celebrated.
