For someone who preaches peace and love, Roger Waters picks a lot of fights. The 73-year-old, who regularly speaks out against far-Right politicians and “greedy” corporations, has been feuding with former Pink Floyd bandmate Dave Gilmour for more than 30 years and revels in stirring arguments.

“Of course I’m belligerent,” announces the four-time divorcee when we meet in a recording studio in New York. Considering the dedicated way in which he has pursued his vendetta against Gilmour, I suppose this shouldn’t come as a surprise. But, with millions in his bank account and a major Pink Floyd retrospective about to open at the V&A Museum in London, to which Waters has given his blessing, I had assumed he might have mellowed.

Not a bit of it.
