Yesterday, Roger Waters did the keynote Q&A at the Billboard Touring Conference and Awards 2013, at the Roosevelt Hotel in New York.

The 80-minute discussion covered a number of subjects, not least his long-awaited new album which is now moving apace. ROlling Stone noted that 'his succinct synopsis of the album's storyline included the character voices of a six-year-old Northern Irish boy and his grandfather who comforts the child after he's had violent nightmares which include children being killed. The grandfather "enters into a covenant with the boy that he will take him on a quest to find an answer to his question, 'Why are we killing the children?' And that's what the record's about," Waters explained.'
