He could have literally been doing anything, musically, that he wanted to do. And I would think of it like I would think of it like Jimi Hendrix, where there's no real way to predict it, because he could have done anything. He had a way of playing the most beautiful songs you've ever heard and singing them, and still with the way that he sang, create a bit of an uncomfortable edge to it if he felt like it. And he did that mostly with his voice.
