This whole thing smacks of the whole authenticity in music canard. True, there are ground-breakers who rupture a bloated or stale era, but ultimately, save for the few laboring earnestly in their art as they strive for innovation, most eventually want to make a nice living.
Two images I remember strikingly along these lines:
1. In the early 90s, Henry Rollins splashing in his hot tub mockingly singing 'Anarchy in the UK' on MTV in response to questions regarding his wealth accumulation versus the punk 'ethos'.
2. John Cage in a spoken word passage about an ad agency calling him for a commission:
They said, 'Mr.Cage?'
I said, "Yes".
'Are you ready to prostitute yourself for your art?'
I said, 'Yes'.
