"Polly wrote the words for 'Louder Than Words' to express that there is something magical about the music that the three of us make together," explains Gilmour. "It has a sort of a magic flow that is encapsulated, if you like, by the words 'Louder Than Words.'"

Due November 10 (Nov 11 in North America), the project is a tribute to keyboardist Wright, who died from cancer in 2008 at the age of 65. "I think Rick would be thrilled, actually," says Mason. "I think this record is rather a good way of recognizing a lot of what he does. I think the most significant element was really actually hearing what Rick did because having lost Rick, it really brought home what a special player he was."

"It is a tribute to him. It's very evocative and emotional in a lot of moments," adds Gilmour. "Certainly listening to all of this stuff, it made me regret his passing all over again. This is the last chance anyone will get to hear him just playing along with us in that way that he did.
