I think that in a certain sense, we're concerned about the same issues. How do you accent the progressive, the prophetic, those things that are critical of all forms of injustice, all forms of bigotry, all forms of dehumanizing other people, and yet still allow for a certain kind of flow, linguistic flow, certain kinds of melodies and harmonies in the samplings that take place?

The American Dream is individualistic. Martin Luther King's dream was collective. The American Dream says, "I can engage in upward mobility and live the good life." King's dream was fundamentally Christian. His commitment to radical love had everything to do with his commitment to Jesus of Nazareth, and his dream had everything to do with community, with a "we" consciousness that included poor and working people around the world, not just black people.

We have to be self-critical even in context that we might be critical of, even as we - our pieces appear in it.

Hey, you got something going here. I think we've got a chance for some progressive policy that actually focuses on poor and working people.

What does it really mean to be a leftist in the early part of the 21st century? What are we really talking about? And I can just be very candid with you. It means to have a certain kind of temperament, to make certain kinds of political and ethical choices, and to exercise certain analytical focuses in targeting on the catastrophic and the monstrous, the scandalous, the traumatic, that are often hidden and concealed in the deodorized and manicured discourses of the mainstream. That's what it means to be a leftist. So let's just be clear about it.

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.

And so the question becomes, what you do in the meantime? And you go - if you're forever on the move, especially in the life of the mind; forever reading veraciously, writing, speaking, lecturing, trying to unsettle minds, trying to touch souls, trying to encourage and inspire, on the one hand, but also trying to unhouse and unnerve people, so that they have to reexamine themselves, society and the world on the others. There's tremendous joy in it.
