Even somebody like The Black Keys or Royal Blood, they all have this original roots base to what they do.

There are so many artists who get to my age that get comfortable and just stick in a groove, and I really don't want to do that.

When I discovered blues - I was 12-years-old - I didn't discover it in America where it was from; I discovered it from Fleetwood Mac - the original Peter Green Fleetwood Mac, Saveloy Brown - like British blues interpretations of it,' which then, when I started the liner notes and seeing all these names, I was like, 'Who's Willie Dixon?' Then I go to the record store and ask the guy there and he goes, 'Oh, you don't know anything.' And so, to me, that's the root of most of it anyway.

I don't think about what I can't do or what I shouldn't be doing. I just think there are endless possibilities musically, really.

I'm definitely obsessed about artists and the type of music and the playing and the tone and all that kind of thing - I'm not obsessed about what the best Beatles album is. I just think if The Beatles are great, they're great.

Today, we're even into the whole sweat thing. They'll wear a [suit] jacket like this, but they'll wear it with sweat pants and sneakers. But I do think there is every generation - and it won't be as big as it was when you and I were those ages - but every generation all of a sudden experiences that they want to dress up.

When you look at so much of what we all love, there's either soul-based to it, or it's the blues. It's really the beginnings of any kind of music. It really is; it all starts there. Because after that, it's music of the moment.
