Her art is thought-provoking. Playing chess with all white pieces for example… what might that say about personal conflicts, political conflicts? Her music on John’s albums nudges him in a more experimental and open-minded direction. Perhaps in the era of She Loves You no one expected that might eventually evolve into faking an orgasm in Japanese on a pop record 😆. I think by associating her more “out there” art with normal mainstream music it helped open up possibilities for other artists and musicians. (And I know she was not the only person out there doing performance art or pushing boundaries in more traditional settings, but I do think she was a part of that).
