Now that rock is turning 50, it's become classical in itself. It's interesting to see that development.

I'm not going to talk like I know about politics, because I'm a total amateur, but maybe I can be a spokesperson for people who aren't normally interested in politics.

I've written arrangements for choirs and strings in the past, but I usually write music with my voice or a keyboard and then I'll get someone who is good at writing scores to write it out. Or, if I have the luxury of time, I will go in a room and hear the people perform and then change it through what I hear, not on paper. I can read music OK, but I probably rebelled a little - music changes into something else when you read it.

I feel like the people from Iceland have a different relationship with their country than other places. Most Icelandic people are really proud to be from there, and we don’t have embarrassments like World War II where we were cruel to other people.

Maybe I'll be a feminist in my old age.

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.

When I was 20, political music was the uncoolest thing on earth. But when Bush got elected, that was the first time I started actually reading the news.
