The show is as ambitious as any in Waters' history, but it's his pre-show message to the audience that caught the attention of CNN's Michael Smerconish.
Each 'This Is Not A Drill' show opens with a recording of Waters reading the following message:
If you're one of those "I love Pink Floyd, but I can't stand Roger's politics" people, you might do well to f--k off to the bar right now. Thank you, and please enjoy the show.
Asked by Smerconish about the sentiment, the former Pink Floyd bassist/vocalist defended it as a "really great way to start the show."
"Apart from anything else, it sets a few things straight ... also it encourages a lot of the people who have come to the show. A) because they have listened to everything I've written since 1965 or whenever I started writing songs. So they do know what my politics are and they do understand what my heart is and, sort of, why I'm there," he said.
The message also sets expectations from the outset: there will be politics in Waters' show just like there have always been in his music.
For people who simply don't want to hear it, Waters suggests they'll probably have more fun at the bar. For people who are open to hearing what he has to say, they might find it a rewarding experience.
"Those people, if they sit in a community like my audience is on these shows of 'This Is Not A Drill' on this tour, there is such a great feeling of communication in that room between me and the audience," he adds. "...Because if 'This Is Not A Drill' has a message, it is that we have to communicate, one with the other."
