The former Pink Floyd singer/bassist reveals that he put together demos of all of the tracks he’s recorded so far, and is trying to organize them into a cohesive whole.

“I’m in a room sitting with a guitar, all the demo recordings and a legal pad and a pen, shoveling things around and scribbling things down,” Waters explains. “It’s an attempt to come up with a shape, a cartoon sketch of what this painting may be when it’s finished.”

He adds that in conjunction with arranging the new tunes, he’s imagining how he would perform in a concert setting.

“The device that I’m using to do that is to think of it as an arena show, because I do think I have one more in me,” Roger maintains, adding, “I’m trying to figure out how to juggle all these new tunes with old tunes as well into a cohesive arena show that I can get some bums into seats with.”

Waters’ last few tours, of course, have been focused on a theatrical multimedia performance of Pink Floyd’s 1979 concept album, The Wall, but he says he feels like his fans are now ready to hear something new from him.

“It’s very exciting but also a very challenging and scary time,” he tells Rolling Stone. “Once you get into the meat of the thing you’re starting to say, ‘Mmm, maybe we should do this with the keyboard part, or maybe that tempo isn’t quite right. Or wait, maybe this transition from this theatrical scene in the next one needs tweaking a bit.'”

Waters’ The Wall Live tour ran on and off for three years, from September 2010 to September 2013. As previously reported, his recent film Roger Waters The Wall, which features footage from a number of dates on the trek, will be released on DVD and Blu-ray on December 1. Meanwhile, Roger admits that he’s starting to get the itch to hit the road again.

He tells Rolling Stone that after his recent one-off performance at the Music Heals benefit concert in Washington, D.C, to aid veterans and wounded military members, he “got real charged up,” noting, “Half of me is going, ‘I can’t wait to get back, and I can’t wait to put this idea to the test and get the thing out.'”

Waters also talks about his relationship with Pink Floyd’s other two surviving members, drummer Nick Mason and singer/guitarist David Gilmour.

“Nick Mason and I adore each other,” he declares. “We’ve been friends for almost 50 years. There was a brief schism when I left the band, and it was completely understandable, but it was relatively brief and we’re great, great friends now.” Waters adds that he and Gilmour “have never been friends at all, so we don’t socialize or have anything to do with one another, really. And I’m content with all of that.”
