Despite the unseasonable cold weather, summer has arrived in London with the opening of the annual Summer Exhibition at the Royal Academy. This year’s exhibition benefits from some drama, for example Anthony Caro’s monumental sculpture in front of you as you enter the galleries, and a more spacious hang, except in one gallery. Gone are those side screens full of small prints and watercolours, thank goodness. Architecture permeates – not only does it has its own gallery as usual but models, paintings and photographs of buildings spread throughout the show. The star is undoubtedly Grayson Perry’s series of tapestries The Vanity of Small Differences, inspired by William Hogarth’s A Rake’s Progress – but given a 21st century twist.
