It's one thing to be indebted to a playwright, as Tom Stoppard and Harold Pinter have been at different times to Beckett, or Sondheim's latest musical is to Sartre. But Conor McPherson's The Brightening Air – the title itself is derived from Yeats – comes so fully steeped in Chekhov that you may wonder whether this portrait of rural Ireland in 1980s County Sligo hasn't bled into provincial Russia from nearly a century before, or vice-versa.

Luster’s fifth track “Halo” has the lyric “mystical creatures… of Éirne,” referencing the Irish river and lough of the same name – both of which are associated with a mother goddess. Earlier, the album’s opener is a short, ambient-styled, scene-setting instrumental titled “Réalt,” where birds, wordless vocals and a harp are heard. Réalt translates from Irish Gaelic as “star.”

“I was born with the ability and the demon to write. I have been punished for it constantly.” Written and directed by Sinéad O’Shea, this fascinating documentary is a testimony to Edna O’Brien’s rebellious talent, her prolific output – a novel a year for a while – and her star-studded socialising. It includes archival footage, some of it against the backdrop of Irish politics, as well as final interviews in which she looks frail but still glamorous in a sequined indigo cardigan, recorded by O'Shea not long before O'Brien died last year, aged 93.

A lot hung upon the delivery last night of Henning Kraggerud, whom I last witnessed leading performances of Strauss’s Metamorphosen and some of his own music at the head of a mine in Svalbard: he was announced at the beginning of the concert as the Irish Chamber Orchestra’s new artistic partner, following the likes of another instrumentalist-composer, Jörg Widmann, and fellow violinist Thomas Zehetmair. So did he triumph? Beyond wildest expectations.

An Irish adaptation of Garcia Di Gregorio’s acclaimed 2008 film Mid-August Lunch, director Darren Thornton’s Four Mothers is the story of Edward (James McArdle) and his 81-year-old mother Alma (the excellent Fionnula Flanagan), who has had a stroke and can only communicate through an iPad. The stairlift is in constant use, as is her bell. And there are jokes about pouffes.

Imagine if Bach had set Cardinal Benedetto Pamphili’s allegory of Beauty breaking free from Pleasure with the guidance of Time and Enlightenment: he’d probably have hit the spiritual highs. The 21-year-old Handel, at least as this multifaceted performance so vigorously and poetically argued, plumps for hedonistic delights.

Let’s finally face the elephant in the room: the most popular Viennese operetta, packed with hit numbers, no longer works on the stage as a whole. The central party, yes, never more high-energy delight than here, with a cast of 13 and 10 instrumentalists on stage. As for the rest, not even the likes of Richard Jones, Harry Kupfer and Christopher Alden have won a total victory. Davey Kelleher comes closer, but the high jinks can still be wearing in the outer acts.

“You know what they say: where there’s livestock, there’s dead stock,” says Jack (a brilliant Barry Keoghan). Never a truer word. There’s an awful lot of dead and maimed stock – sheep, to be precise – in Christopher Andrews’ gory, gloom-ridden directorial debut. Animal lovers will want to avert their eyes. The film is undeniably powerful, with fine performances, but the unremitting violence ends up feeling cartoonish and empty.

Anglo-Irish author Catherine Airey’s first novel, Confessions, is a puzzle, a game of family secrets played through the generations. Set partly in New York and partly in a small town in Donegal, the book moves back and forth through time and space becoming, in the process, a compulsive read: a fascinating Russian nesting doll of family trauma.

There’s nothing like an anodyne new(ish) work to give a masterpiece an even higher profile. Rachel Portman‘s Tipping Points, promising to address climate change issues, was so bland and featureless it could have been composed by AI. Any one bar of Shostakovich’s Tenth Symphony, on the other hand, shows originality of throught within a tradition, and unlike the Portman near-vacuum it challenged the musicians of the National Youth Orchestra of Ireland to the limits.
