Pink Floyd founder-member Roger Waters brings his “Us + Them” tour to Zagreb’s Arena; a visually stunning show that has already been half the way round the globe. The set is likely to be a long one, drawing heavily on mid-period Floyd; key cuts from Dark Side of the Moon, Wish You Were Here, Animals and The Wall are certain to get a run-out, with Waters’ post-Pink solo work pushed discreetly into the background. With a perfectionist like Waters around there are unlikely to be any complaints about the performance or the sound.
