Roger Waters has been talking to RollingStone.com about his activities since finishing The Wall Live on September 21st, in Paris, France. Clearly determined to keep working, rather than taking a much deserved rest after the rigours of the tour, he's been hard at work on his new album. "I finished a demo of it last night," he tells Rolling Stone. "It's 55 minutes long. It's songs and theater as well. I don't want to give too much away, but it's couched as a radio play. It has characters who speak to each other, and it's a quest. It's about an old man and a young child trying to figure out why they are killing the children."

Rolling Stone asks if he's likely to tour the new album once it is complete. "I'm suffering a little bit of withdrawal after ending the Wall tour," he says. "It's sort of a relief to not have to go out and do that every night, but they're such a great team. There were 180 of us together everyday. That piece was very moving every night."

Waters continued: "I can't top that tour. First of all, you have to accept the fact that I'm not going to live forever. I'm 70 years old. You just have to accept that when you do something as enormous as that tour. The hardest thing in the world is thinking of something to do, so going and doing it is a reward in itself."

He doesn't rule out the possibility of reviving The Wall at some point, and happily recalls which city had the loudest fans of all. Read more at RollingStone.com.
