Dylan was asked about how much improvisation was involved in his musical process to which he replied, "None at all."
The legend explained that there is no way you can change the nature of a track once you've invented it. "You can set different guitar or piano patterns upon the structural lines and go from there, but that's not improvisation. Improvisation leaves you open to good or bad performances, and the idea is to stay consistent. You basically play the same thing time after time in the most perfect way you can."
Dylan also indicated that most of his recent songwriting were composed in a "trance state". "The lyrics are the real thing, tangible, they're not metaphors," he explained. "The songs seem to know themselves, and they know that I can sing them, vocally and rhythmically. They kind of write themselves and count on me to sing them."
Dylan expressed that writing 'I Contain Multitudes' was like trance writing. "It's the way I actually feel about things. It is my identity and I'm not going to question it, I am in no position to. Every line has a particular purpose," he told NY Times. "Somewhere in the universe, those three names must have paid a price for what they represent and they're locked together. And I can hardly explain that. Why or where or how, but those are the facts."
When pointed out that Indiana Jones was a fictional character, Dylan replied that the John Williams score brought Jones to life. "Without that music it wouldn't have been much of a movie. It's the music which makes Indy come alive. So that maybe is one of the reasons he is in the song. I don't know, all three names came at once."
