I'm possibly retro-fitting my answer here, but that film clip feels like the band, feels like it fits well with the music, I think that's why that clip came to my mind in relation to the produce-generica of the original article.

The clip incorporates images of the band and, as @DoktorDelta pointed out (which I didn't know before), it was trained on art created by some of the band members. It also totally fits the psychedelic rock vibe, not just for this song, but also into the canon of psychedelic rock film clips and general psychedelia media.

Yes absolutely. A good analogy would be Gibhli. If you saw a Gibhli styled ad for say your local restaurant would you consider it art.

Now rewind, uninvent AI and then would you consider that same ad art?
