With the White Stripes we were trying to trick people into not realising we were playing the blues. We did not want to come off like white kids trying to play black music from 100 years ago so a great way to distract them was by dressing in red, white and black.

If you're asking if I would be foolish enough, or insulting enough, to write about people in my life that I respect and sell it to the masses as a "break-up song," I can't imagine doing that to people I love.

You hear a lot of people, they turn 40 and it really bugs them and they get depressed or whatever. I don't know - I just don't feel that way. I feel 19 years old all the time. I mean, it's not a lie. I could easily say, God, I feel 70. Or maybe I seem like I'm 70 or 200 or something to other people, I don't know. My brain feels 19 all the time. And that's a good spot.

A riff can take on the aspect of a chorus in a listener's psyche.

I dabbled in things like Howlin' Wolf, Cream and Led Zeppelin, but when I heard Son House and Robert Johnson, it blew my mind. It was something I'd been missing my whole life. That music made me discard everything else and just get down to the soul and honesty of the blues.

Amy Winehouse: Did she invent white soul? Wearing a beehive? No. But she did something brand new and fresh, altogether as a package, and you see who's in her wake, from the Duffys to the Lana Del Reys. Adele selling 20 million records? That would not have happened if Amy Winehouse was alive.

A songwriter's heart is pure when they have the desire to keep digging deeper into music. And invariably, when you dig deeper it always leads you into the past.
