Martin Luther King was an extremist of love.

It's a spiritual malnutrition tied to a moral constipation, where people have a sense of what's right and what's good. It's just stuck, and they can't get it out because there's too much greed. There's too much obsession with reputation and addiction to narrow conceptions of success.

For me, music is in no way ornamental or decorative, it's constitutive of who I am. And that's why, when I say I'm a blues man, that's a very serious vocation - to muster the courage to find your own unique voice, to forge your distinctive style in the world, to leave your imprint in the sands of time in such a way that your singularity, your individuality, remains something that people have to come to terms with.

I'm not romanticizing black people, because we've got gangsters like everybody else.

I try to, in my own fallible way, speak the truth.

We have a market-driven society so obsessed with buying and selling and obsessed with power and pleasure and property, it doesn't leave a whole lot of time for non-market values and non-market activity so that love and trust and justice, concern for the poor, that's being pushed to the margins, and you can see it.

The question is really how do we think seriously about this mechanism called a market. It ought to be determining not values but prices.
