Where have all the misbehaving rockstars gone?

Marie picked up some prints a couple of years back, at an art gallery opposite her work which was closing down. Nothing pricey, just lowish print runs of some pretty pictures including this image from a series called Operation Magic Kingdom. We promptly stuck them on the walls, and I never thought to investigate who these prints were by.



It turns out they are by James Cauty, who in previous incantations was a member of the KLF, and a member of the Orb. Damn these multitalented people. Cue my favourite KLF song:



Which brings me on to a comparison with the music stars of today.

When James Cauty was in the KLF they burnt one million pounds in cash, and enthusiastically filmed themselves doing as some kind of expensive performance art. You could argue this enthusiasm was misplaced, given that Cauty publicly regretted setting fire to a million quid about ten years after the event, but rock stars have to engage in excessive behaviours, that is the rules.
(And yes, I am aware of the contradiction in dictating rules of rockstar misbehaviour which involve breaking social norms and rules.)

Where are the comparative excesses and/or ideologically driven impulses of today’s music stars? All the modern music I come into contact with feels commercially sanitised, and rock star excesses seem to be toned down and/or eliminated.

Exhibit 1: Iggy Pop - back in the 1970s he was pioneering stage diving and rolling around on stage in broken glass, and now he shills car insurance. I mean, really?
Yes his level of pharmaceutical consumption circa 1970s was completely unsustainable long term, but Keith Richards is still alive and falling out of coconut trees so at least some of the old guard have managed to avoid descending into wholesale consumerism.

Or have I become so jaded and cynical that nothing rock stars do is shocking or new? Is my nostalgia for rockstar misbehaviour misplaced?
