Huh? If, at this point in her career, insuring the future of her family is an issue, she should be finding a good lawyer and suing her management. We're talking about someone who has been able to successfully bridge the chasm between jazz and popular music, who has released nearly a dozen well selling CD's and who plays to sold out houses where ever she goes. I hardly think money is an issue or a driving force behind her decision making. I'll double down on that assertion by virtue of the fact that she's married to Elvis Costello.
You might be right. But that would be an assumption.
Regardless, I certainly am not going to forego my right to complain about talented artists making commercial crap just because it feeds them and their families. They can do what they want, sure, but saying we can't carp about it? Absurd. You could justify practically everything anyone has ever done on those grounds.
I'm not trying to silence anyone. In truth, the music is not my favorite either. I just try to give the artist the benefit of the doubt, given that some of her other work has been great (in my opinion).
