Revolution: Russian Art 1917-1932, Royal Academy

An exhibition of Russian art purged of the artists who promoted the revolution

This must be the most depressing exhibition I have ever seen. Dedicated to the leaders of the Russian Revolution, the first room features official portraits by Isaak Brodsky of Lenin and Stalin plus drawings and models of Lenin’s vast mausoleum in Moscow’s Red Square.

A handful of new galleries, British modernism revived and old masters revisited

Before we consign this miserable year to history, there are a few good bits to be salvaged; in fact, for the visual arts 2016 has been marked by renewal and regeneration, with a clutch of newish museum directors getting into their stride, and spectacular events like Lumiere London, and London’s Burning bringing light in dark times.

Intrigue: James Ensor by Luc Tuymans, Royal Academy

A treat full of trickery: Belgium's master of the grotesque through the eyes of a fellow countryman

James Ensor? Who he? A marvellous Anglo-Belgian artist (1860-1949) little known outside Belgium, whose masterpiece, The Entry of Christ into Brussels in 1889, 1888, is a trophy painting at the Getty, California. It is present here in his own print version, its crowd scene mixing reality and fantasy typical of his wild imagination and extraordinary technical skill. 

Abstract Expressionism, Royal Academy

LAST WEEK ★★★★★ ABSTRACT EXPRESSIONISM, ROYAL ACADEMY Energy, alcohol and bucketloads of paint: a triumphant reunion for New York's most exciting artists

Energy, alcohol and bucketloads of paint: a triumphant reunion for New York's most exciting artists

Gorgeous, sumptuous, thrilling: here comes Abstract Expressionism riding into town, the first major overview in London since its own contemporary heyday in the 1950s. A clunky, unappealing label for such fabulously appealing stuff, it's best just to relax and enjoy this total immersion, for colour and gesture can never have been combined to such memorable effect. Nurtured by the melting pot of New York, this was the first homegrown group of American artists, its activities destined to put New York on the international culture map, wresting the crown of art capital from Paris.

David Hockney RA: 82 Portraits and 1 Still-life, Royal Academy

An ongoing series of portraits has served as a tonic during difficult times, but its value is more personal than artistic

The opening image of this new David Hockney exhibition – a sketchily painted portrait of a seated man, slumping heavily forward, his head buried in his hands – could be a portrait of Brexit despair.

Opinion: Paintings with nothing to lose but their frames

OPINION: PAINTINGS WITH NOTHING TO LOSE BUT THEIR FRAMES Sometimes frilly, always unwanted: a new show highlights the curse of frame shadow

Sometimes frilly, always unwanted: a new show highlights the curse of frame shadow

The dazzling, controversial, fascinating exhibition In the Age of Giorgione at the Royal Academy inadvertently provides a striking example of an unavoidable and perhaps insoluble problem common to almost all exhibitions of painting – especially those with a high proportion of loans – in public museums and galleries.

In the Age of Giorgione, Royal Academy

IN THE AGE OF GIORGIONE, ROYAL ACADEMY A tantalising evocation of 16th-century Venice, but the great painter remains elusive

A tantalising evocation of 16th-century Venice, but the great painter remains elusive

Much is made of the mystery surrounding Giorgione, a painter of pivotal influence, about whom, paradoxically, we know almost nothing beyond the manner of his death. He died in a Venetian plague colony in 1510 aged about 33, and was as elusive in the 16th century as he is today, his paintings highly sought after but hard to come by, and by the time of his death already invested with mythic status.

Painting the Modern Garden, Royal Academy

PAINTING THE MODERN GARDEN, ROYAL ACADEMY Monet triumphs in a celebration of nature tamed

Monet triumphs in a celebration of nature tamed

Painting the Modern Garden explores the interstices between nature and ourselves as revealed in the cultivation of gardens, that most delightful and frustrating of occupations, and an almost obsessive subject for many artists. About 150 paintings from the 1860s to the 1920s, gathered together from private and public collections in North America and Europe are on view, amplified by letters, plans, documents, photographs and illustrated books on horticulture.

Jean-Etienne Liotard, Royal Academy

JEAN-ETIENNE LIOTARD, ROYAL ACADEMY Master chronicler in line and colour offers a beguiling glimpse of the age of reason

Master chronicler in line and colour offers a beguiling glimpse of the age of reason

Unswervingly confident, relaxed and assured, the élite of the 18th century are currently arrayed on the walls of the Royal Academy, gazing down at us with the utmost assurance of their unassailable place in the world, bright eyed and dressed to match. The swirls of public reputation are unpredictable: here is a revelation, the art of one of the most successful and highly prized portraitists of his day, Jean-Etienne Liotard (1702-1789), now almost completely unknown except to specialists.

Ai Weiwei, Royal Academy

AI WEIWEI, ROYAL ACADEMY The Chinese activist is more powerful as a symbol of dissidence than as an artist

The Chinese activist is more powerful as a symbol of dissidence than as an artist

Ai Weiwei’s first major survey in the UK is a better looking exhibition than I had anticipated, but what it gains in looks it sadly lacks in substance – backstory and information not being quite the same.
