Here's an excerpt from an interview with the New York Times taken shortly before Jack's solo performance at the South by Southwest Festival:
When you announced that the White Stripes were officially breaking up, you said, “The White Stripes do not belong to Jack and Meg anymore. The White Stripes belong to you now, and you can do with it whatever you want.” What did you mean by that?
People say, “Why didn’t you do this? Why didn’t you do that?” Or, “Don’t you owe something to somebody, or to yourselves?” All those questions. That line was the idea of explaining to them that at a certain point as an artist, you paint your painting, you do your sculpture or your music, and you release it into the world. You don’t own it anymore. You have no control over it. You put it out there to share with other people. You can only hope for the best.
Were you thinking literally, that people would take White Stripes tracks, remix them and say, “O.K., they said it doesn’t belong to them anymore.”
It was a side comment in a funny way about the way things are done now with that. But I meant in a more romantic sense.
