I came to the comments to find something that further challenged my preconceptions of Ono, as the article did, and then I see the usual cartoonish example carted out when criticizing her, which everyone has already seen before. A better example is elsewhere in the comments:

I get it. It's the stuff that only music nerds would be interested in. But I'm not sure why Frank Zappa and Captain Beefheart aren't anywhere near as maligned as Yoko is, but celebrated as mavericks. And even still, experimental artists like these push the artform as a whole forward, to the point that their original innovation becomes co-opted into the mainstream sound and forgotten.
