Whether interpreting a Roger Waters' second-person rumination from forty years ago on Pink Floyd's Wish You Were Here or singing a verse which wife/lyricist Polly Samson (who also joins us) wrote last night, throughout his long illustrious career David Gilmour has sung the thoughts and observations of others. "It takes thought and it takes concentration," David admits, "I mean you have to live and breathe and believe the words you're saying, and with most of Roger's (Waters) brilliant lyrics and with Polly's lyrics too, I find that I can do that."

Since his first foray apart from Pink Floyd in 1978, Rattle That Lock is only Gilmour's fourth solo venture, and his first since 2006's On An Island. On Rattle That Lock Gilmour gets his groove on with the song "Today", flirts with pop on the catchy title track, reminds us all of the human toll of war with "In Any Tongue" , and may be a Grammy contender for instrumental of the year with "And Then...".

Speaking to InTheStudio host Redbeard, David Gilmour addresses perhaps the single most divisive yet insidious human response. "I think there is still an enormous amount of prejudice against all sorts of people, women, people of different sexual orientation, religions. The world is rife with prejudice still and we're deluded if we think it's gone away... I think it will take centuries for a lot of the prejudice at the core of people's being to go away."
