Rodger Waters has definitely gone off the rails and seems to go out of his way to bite the hands the feed him. As he grows older, he goes on rants and makes statements that not only piss of fans, but he also starts to tarnish the name Pink Floyd in the process. His resent comments have even lead to the possible cancelation of a 500 million dollar sale of the rights to the Pink Floyd catalog. I was going to go to the show, but videos and resent interviews led to the decision not to.
Pink Floyd was a group and together they made great albums. However, in his mind, he was the only one that mattered and the other members of the band where not really members but just hired hands he tolerated till he "kicked them to the curb". I would much rather to listen to David Gilmour's solo records or even PF sands Rodger as it is just a better musical experience without hearing how we all suck and are terrible people.
All one has to do is look and listen to music from "The Division Bell" tour an Rodger's most current tour and one can easily see Division Bell is vastly superior in every measurable data point.
Also - a few commenters mentioned U2. While I agree that there was a period of political ramblings, it was Bono who lead the charge just like Rodger. The difference is Bono matured and his message improved. He also puts his money where his mouth is, donating vast amounts to charities and performing good deeds around the world. So, in Bono's case, I give him a tone of slack as I think he is a good cat but can not say the same for Rodger.
I will still listen to Pink Floyd but feel Rodger is doing himself and the band a disservice.
