"I'm no longer beholden to the sacredness of the recorded song as some kind of ultimate standard by which every performance of the song is measured. I like to diversify, that there are multiple versions of every song. And the songs incorporate a lot of improvisation, and an element of chance, and I think that's exciting. There's no one true formulation of a song, they have various manifestations depending on the space we're in. I like that."
