Roger Waters is perhaps the greatest rock and roll showmen thanks to his great visual compilations, which are second to none in rock and roll history. There is absolutely no denying his emotional impact through his words, lyrics and visuals. He is the king of the bleeding hearts; a liberal I can actually respect. Of course, like most other liberals, he is very good at pointing out the problems of civilization through the ages, but not very helpful when it comes to solutions to prevent war, starvation, genocide, homelessness, religious persecution, and other injustices of recent history. I am kind of reminded of the Assistant Principal in South Park when I see displays like this. "Drugs are bad, OK?, War is bad, OK", Genocide is bad, Ok?, Starvation is bad, OK?. Yes, Mr. Waters, we know. What separates Mr. Waters and Pink Floyd from the rest of the bleeding hearts is his ability to tap into the isolation and dismay of millions of people in the world who feel there is no hope, no chance for human salvation, no chance for human beings to overcome their despicable shortcomings, and no chance to break through that psychological wall of bureaucracy, indifference, callousness, and authoritarianism. Yes, all these things are bad, too, OK? But the real questions beg to be asked: What should we do about it? How should we live our lives, work, raise families, and age in such a world? How can we make the world a better place for our children and grandchildren? Those answers are not provided by Mr. Waters, nor should they be. He is not there to give us all the answers; he is there to ask crucial questions. And he does so with style. Highly recommended.
