Niall is unwell. Very unwell. Very, very. There’s a lot going on in his head. He can’t really hold things together. Evidence? Well, he’s lost his job and his girlfriend Natalie has left him. So, as desperation increases, he decides to phone his big sister Brigid – the trouble is, it’s 3 o’clock in the morning.

Change, we're often told, is the engine of drama: people end up somewhere markedly different from where they began. So the first thing to be said about Nick Payne's blistering new play The Unbelievers is that its concept is as brave as leading lady Nicola Walker's take-no-prisoners performance.

It was guaranteed: string masterpieces by Vaughan Williams, Britten and Elgar would be played and conducted at the very highest level by John Wilson and his Sinfonia of London.

Would a rarity by Arthur Bliss and a slow movement from a Delius string quartet arranged by Eric Fenby match them? The otherworldly Delius did; the muscular Bliss, despite special pleading by John Wilson in an affable spoken introduction, sounded magnificent and was worth hearing, but not quite on the genius level. 

Jean Genet’s 1947 play has been quite a clothes-horse over the years, at times a glamorous confection dressed by designers, and regularly shape-shifting and gender-fluid. Cards on the table: I have disliked most productions of it for this odd vacuity, which allows it to become unmoored so radically from its source, the real-life case of a mistress and her daughter murdered by their two maids.

The return of this entertaining political drama is always welcome, though its soap-tinged mix of transatlantic politics and volatile personal relationships is beginning to look a little too genteel for our current age of ever-worsening crises.

There was a time when Gilbert & George made provocative pictures that probed the body politic for sore points that others preferred to ignore. Trawling the streets of East London, where they’ve lived since the 1960s, the artist duo chronicled the poverty and squalor of their neighbourhood in large photographic panels that feature the angry, the debased and the destitute.

To hear Kadiatu Kanneh-Mason speaking live is to hear a woman who very much recognises that her lifelong mission to challenge the perception of who should play classical music is ongoing. Though she has given birth to seven children who have gone on to be stand out classical musicians, she knows that there are still those who deny them the recognition they deserve because of the colour of their skin.

Another day, another shooting: this is Florida, USA, where the "Stand Your Ground" self-defence law allows people to use lethal force when they perceive a threat to their lives. The idea may be shocking to Britons, but such laws have become prevalent in America, even though they may be providing cover for straight-up murder.

Bryony Kimmings’ new show – her first in five years – was created to celebrate the opening of Soho Walthamstow, the previously neglected Art Deco beauty that’s now one of London’s shiniest venues. She uses every bit of its vast stage to great effect and even manages to get a chunk of the audience on it for its witty epilogue, of which more later.

Phyllida Lloyd’s production of La Bohème for Opera North is over 32 years old but still feels young. And for its audiences it still has the ability to capture – as the opera is designed to – the experience of youthful love and separation, its ecstasy and its heartbreak.
