There are some exhibitions worth seeing because they contain work so startlingly fresh and provocative they prompt a collective deep breath (for example, Kara Walker at Sikkema Jenkins & Co. in New York earlier this year). Then there are those you see because you missed them at the time they provoked such a reaction. It’s now nearly 20 years since Tracey Emin presented My Bed, which places it firmly in the latter category. Despite not winning the Turner Prize, the stained bedsheets and general detritus which so shocked the public fostered a notoriety that pushed visitor figures to a record high at Tate Modern, where it was on display in 1999. The piece returned to the Bankside museum in 2015, but it’s on the move once again, this time to Margate, where it will be displayed alongside Emin’s edit of a selection of seascapes and stormy skies by J.M.W. Turner. If you make the journey to Kent, make sure to catch the Jean Arp exhibition too. The first in the UK since his death in 1966, the show includes many works never exhibited before in the UK.
