I'm unable to really write the kind of song that doesn't have a visual element, which most songs don't.

It was about the preciousness of that, and how they viewed those birds as art, as something valuable. I didn't care one way or another back then, but now, thinking about my grandparents - who are still alive but getting older - I see the birds as sort of time capsules. Now I go home during the holidays and they hold a lot of weight in terms of nostalgia and memory. Now they mean everything.

I always thought my records were number one; it's just the charts didn't think so.

I know when I sit with my band members and we're playing back a song that we've done, I know that they're experiencing it in a completely different way and hearing stuff that they're alerted to because the way the interpret the world is through their ears. Mine is through my eyes.

Songs need to have the ability to change and to grow for sure. They take on lives of their own. Some songs just don't have that capacity. They're locked within a period of time. And as soon as you take them out of that period of time, they die very quickly.

I'm not saying this in a condescending kind of way, but it's quite simple: The making of America was a heroic thing. Australia has a much murkier, much more complex view of its history. It's just full of all these open wounds we don't really know what to do with.

There are methods to creating a mayhem that sounds different from your usual mayhem. Because mayhem and a heavy drum backbeat end up sounding like Green Day or something. But if you put a different beat within it to create some air and lightness, the chaos comes through better.
