Raqib Shaw’s richly imagined scenes at Pace Gallery are dominated by the verdant Kashmiri landscape and a tribe of cavorting and lounging peacock-headed characters, who echo the poses of picnicking Parisians lounging in a park in Manet’s 1862 painting Le Dejeuner sur l’herbe. Intricately painted in vibrant enamel colors, Shaw’s new paintings are a feast for the eyes. (On view in Chelsea through May 18th).
