You could not attend a Roger Waters concert without him preaching politics. If you listen to the preaching, you would not be able to ignore it and it ruins the act. He went on for many minutes eschewing reality. Ego maniac.
Neil is one of the artists who charges more for his albums, more for this concerts, and frequently releases material that is half-hearted. I like the man, but he cheated on me by taking my money numerous times until I finally wised up. The last thing I liked from him was Psychedelic Pill as "Walk Like a Giant" is a great jam, albeit the extended ending of the song is a hard listen. We are talking 5-6 minutes he took to end the song. WTF? I just think Neil has an equally enormous ego and never listened to anyone with respects to his music career. Typically, Canadian musicians are much less egotistical than American counterparts, but knowing what I know about his life, he is fundamentally an American.
Similar to Bob Dylan, Neil can't sing. Dylan's most recent tour was a disaster. He comes out on stage in a wild costume and ridiculous hat, sits down at the piano, and mumbles for 45 minutes. Highway robbery.
