"I love being there, I love America, I love the feeling of the wide open spaces, I love the deserts, I love the mountain ranges, I even love the cities. So having fallen in love with America over the years that we've been there on tour, I then had to 'deal with' America and the way it was affecting me, because America's having such an effect on the world at the moment. On this record I had to deal with it on a political level for the first time, if in a subtle way."
