My greatest influence has been the blues. And that’s a literary influence, because I think the blues is the best literature that we as black Americans have. […] Blues is the bedrock of everything I do. All the characters in my plays, their ideas and their attitudes, the stance that they adopt in the world, are all ideas and attitudes that are expressed in the blues. If all this were to disappear off the face of the earth and some people two million unique years from now would dig out this civilization and come across some blues records, working as anthropologists, they would be able to piece together who these people were, what they thought about, what their ideas and attitudes toward pleasure and pain were, all of that. All the components of culture.
