Should Linda Ronstadt have been able to express her politics at a Vegas concert? John Rockwell: “Art exists in a context inevitably conditioned by politics, and politics and the values behind it express themselves in art. There is an obvious linkage between mass commercial art and politics, quite apart from individual actors and directors and pop musicians espousing a political view. Popular art makes money by reflecting what its producers think people want. But given the leftward tilt of Hollywood and our coastal cultural elites, the right has reason to complain that commercial television, films and music often advance a left-leaning political agenda.”
