Myra Hess was one of the most important figures in British cultural life in the mid-20th century: the pre-eminent pianist of her generation and accorded “national treasure” status as a result of the wartime lunchtime concert series at London’s National Gallery, which she singlehandedly masterminded through 1,698 concerts between 1939 and 1946.

Van Gogh: Poets & Lovers includes many of his best known pictures and, amazingly, it is the first exhibition the National Gallery has devoted to this much loved artist. Focusing mainly on paintings and drawings made in the two years he lived in Provence (1888-1890), it charts the emotional highs and lows of his stay in the Yellow House in Arles, and the times he spent in hospital after numerous breakdowns.

What a feast! Congratulations are due to the National Gallery for its latest blockbuster After Impressionism: Inventing Modern Art. Such a superb collection of modern masters is unlikely to be assembled again under one roof, so this is a once-in-a-lifetime, must-see exhibition.

Despite the fact that it’s a cruel depiction of an aging woman, I have always loved Quinten Massys’ The Ugly Duchess (pictured below, left). The Flemish artist invites us to laugh at an old dear who, in the hope of attracting a suitor, has tucked her hair into a horned headdress and decked herself in a décolleté gown that exposes her wrinkled cleavage.

There stands Lucian Freud in Reflection with Two Children (Self-portrait), 1965 (main picture) towering over you, peering mercilessly down. Is that a look of scorn on his face or merely one of detachment? His two kids seem to be squirming and giggling beneath their father’s unblinking stare. Who wouldn’t be, especially when the huge lamps hanging overhead are reminiscent of an interrogation chamber? All the better to see you with, my dear.

Across the pond Winslow Homer is a household name; in his day, he was regarded as the greatest living American painter. He was renowned especially for his seascapes and his most famous painting, The Gulf Stream, 1899/1906 (main picture) features in the National Gallery’s retrospective.

I’m a sucker for traditional vitrines and the procession of old style display cases installed by Ali Cherri in the Renaissance galleries of the Sainsbury Wing look very handsome.

American artist Kehinde Wiley may be best known for his photo-realist portrait of Barack Obama, but painting powerful black men is not the norm. More often he elevates people met on the street in Brooklyn, Dalston or Dakar to positions of pseudo authority by inserting them into pastiches of history paintings honouring the rich and powerful.

It’s been described as “the most improbable story that has ever happened in the art market”, and The Lost Leonardo reveals every twist and turn of this extraordinary tale. In New Orleans in 2005, a badly-damaged painting (pictured below left) sold at auction for $1,175.

It has been well-documented over the last few months that there has been an upsurge in listener numbers for many radio stations offering classical music – notably BBC Radio 3, Classic FM and Scala Radio – and, during these unprecedented times it comes as no surprise to discover that so many people (of all ages) are finding solace in music which, in some cases, they are turning to for the first time.
