That kind of unease, that melancholy, is of course partly my interpretation, but partly, I think, it's something that's really there [in America] as well. It resonates with this moment and the sort of alienation from the power structure a lot of people feel, as well as a certain amount of desperation, in the hope of disrupting the power structure so they can live better lives. I think in those ways, it's intimately connected to today.

Sometimes the picture is more interesting than what is going on. Sometimes the picture is suggestive of greater things in society or the history of what might be connected to the theme in the pictures and those are worth exploring.

[The Middle East conflict ] just kind of ran its course for me. For a long time I could justify doing it to myself, no matter how irrational it was. It was important to me and my work. And I just don't feel it in the same way any more. When it comes up and it's important to me, I'll do it, but more out of sense of duty than desire - which used to be a big part of it.

It was sometimes provoked by assignments, then I'd go back on my own dime if I really clicked with a place. And sometimes it was just hanging out with my family or friends.

I went out to cover the wars in Iraq and Afghanistan fundamentally [in Buzzing at the Sill] because I was interested in war as a notion and in experiencing it. I was interested in history and how societies form. I was interested in the recent history of what had provoked these wars. So when I finally got out there, I was really seeing the wars through the American perspective, much more than through being embedded with American soldiers and Marines.

I am still covering conflict to some degree. I was back in Iraq. I've covered quite a bit of the Israel and Palestine. But I'm not doing it with the kind of intensity I was before and I'm not seeking out the front line and the kind danger that comes with being at the edge of the war the way I used to.

I'm a constant editor. Every few months or so I make a ton of 4x6 prints. I put them on a magnetic board and I live with them for a while to see what bubbles to the surface. A lot of this was part of Disco Night originally, and I suddenly started realizing, "If I keep working on this because I'm not done and I put all that in Disco Night, how can this be one book? Is it going to be too long and bloated and crazy?".
