It’s taken six years of planning, and is three years late, but finally, this epic Royal Academy show is opening. Originally slated for 2020, but postponed due to the pandemic — of all the Covid delays, cancellations and closures, one for a show where you literally rub up against naked humans is perhaps the most understandable — here it is. It’s been reimagined, lost its original title (After Life), gained a thematic rather than chronological structure. The 76 year-old Serbian performance artist Marina Abramović insists it is the best possible presentation of her work.
