Exhibition of the week
Bridget Riley
The British answer to Jackson Pollock shows how seductive and intoxicating abstract art can be.
De La Warr Pavilion, Bexhill-on-Sea, from 13 June until 6 September.
Other exhibitions this week
Bruce Conner
A cinematic meditation on the atom bomb using footage of tests at Bikini Atoll by this richly subversive Californian artist of assemblage and found stuff.
Thomas Dane Gallery, London, until 18 July.
Tracey Emin and Mat Collishaw at the Aldeburgh festival
Emin’s outdoor sculpture Roman Standard has a harmless little bird instead of an eagle on top, while Collishaw shows his sinister still lives of last meals on death row. The Aldeburgh festival also includes work by Damián Ortega.
Aldeburgh festival, Snape Maltings, Snape, Suffolk, and other venues until 28 June.
Great British Drawings
Gainsborough, Turner, Hockney – they all feature in this exhibition at a museum that possesses one of Britain’s finest collections of draughtsmanship.
Ashmolean Museum, Oxford, until 31 August.
Shoes: Pleasure and Pain
Salvador Dali would have loved this celebration of the stranger side of shoes. Strangest of all, it is sponsored by the sensible-shoe purveyor Clarks.
V&A, London, until 31 January.
Masterpiece of the week
Georges Seurat: The Rainbow, Study for Bathers at Asnières, 1883
Seurat prepared for his great painting Bathers at Asnières – also in the National Gallery, London – with sensitive studies of light and landscape such as this lovely, lyrical painted sketch. His meticulous way of working as well as his fracturing of light make him a major influence on Bridget Riley.
National Gallery, London.
