“Keep here your watch, and never part.” There was a strong symbolism of standing and singing together in the last moments of the Grenfell Tower Benefit Concert. After singing the Lament of Purcell's Dido, Christine Rice made her way back slowly through the orchestra to join the choir. All 150 participants in the concert, operatic stars, young singers, conductor, a special orchestra assembled from various London orchestras joined in for the final chorus of Dido and Aeneas. All had given their services for free to support charities helping Grenfell Tower survivors.

“I’m not in the mood” – “non sono in vena” – sings aspiring poet Rodolfo as he settles down to write a lead article. Was it me, or had the mood not settled by the premiere of the Royal Opera’s first new production of Puccini's structurally perfect favourite for 43 years? The singing was good to occasionally glorious, Antonio Pappano’s conducting predictably idiomatic and supportive.

On the morning of the Grenfell Tower disaster, as the news of the fire gathered pace and gravity, our phones were abuzz with concern for our front of house colleague, Debbie Lamprell, who we knew lived in the tower. We all called her number time and again, sought to reassure one another with optimistic scenarios whereby her telephone may have been left at home as she escaped. My telephone rang again.

When are the big international opera houses going to wake up to the great British talent that is Elizabeth Llewellyn? With her opulent soprano – shaded middle register, full bloom at the top, cutting chest voice – she was born to sing Verdi and Puccini, and her stage presence is undeniable from the moment she steps out.

I’ve seen the future, and it’s semi-staged. The gains here are far more significant than the losses. And where Opera North’s minimalist Leeds Town Hall Ring let Peter Mumford’s video projections fill in the gaps, this new production of Turandot is costumed, lit and directed, lacking only a backdrop. The chorus are squeezed stage right, tightly crammed into the choir seats. The cast gamely do their thing in the narrow space betwixt strings and stage.

For such a macabre, dark work, there’s an awful lot of grinning going on – notably from Opera North’s on-form orchestra, gleefully let off the leash in this most startlingly modern of Puccini operas. Tintinnabulists will swoon at the sight of 13 tuned gongs, and how often do we get to actually see a real cimbasso perched next to the trombones? Conductor Sir Richard Armstrong revels in the opera’s brassier excesses. It’s excessively, joyously loud in places, but I didn’t see anyone complaining.

Listen blind, and it’s hard to believe that this score was written in 1924. Puccini’s stark, declamatory choral writing and outré harmonies sound as fresh as paint, and, until the problematic close, there’s not a wasted note. I’ve rarely heard anything as musically exciting as this production’s first few minutes: a series of savage chords depicting the falling of an executioner’s axe followed by the Mandarin’s angular declamation, sternly dispatched by a nattily-dressed Dean Robinson. All terrific, and then the chorus enter, their combined force powerful enough to dislodge a toupée in the rear stalls.  

Annabel Arden’s staging revels in the physical constraints, the plotting and characterisation much clearer as a result. Alastair Miles’s Timur is a shabby, cowed wretch, his blindness implied with a mere smidgeon of face paint. Sunyoung Seo’s downcast, plainly dressed Liù stands out among the supporting cast, able to reduce her voice to a whisper while losing none of its colour. Rafael Rojas as Calaf is an impetuous, headstrong joy, his high register unchallenged by Puccini's louder tuttis. Set and costume designer Joanna Parker’s sole prop is a giant wobbly throne which begins to teeter precariously. Underneath which we catch a fleeting glimpse of Orla Boylan’s Turandot (pictured right) early on, a terrifying sight in metallic grey and black feathers. Her voice is suitably commanding and steely, only gradually revealing its warmth in the last act. And dressing Gavan Ring, Joseph Shovelton and Nicholas Watts’s Ping, Pang and Pong (below, left) as white faced circus clowns reminds us of their commedia dell'arte roots, the trio making brilliant use of suitcases, surgical instruments and a human skeleton.

Bonaventura Bottone’s Altoun exudes scary authority. Armstrong and Arden ratchet up the tension as the evening progresses, and it’s difficult to suppress a cheer as Calaf solves Turandot’s three riddles. Rojas’s sweet-toned Nessun dorma is utter perfection, aided by immaculate chorus work, and what a surprise it is to hear this iconic aria in context: Puccini‘s refusal to linger a real slap in the face. It’s the final scene which doesn’t quite work. Turandot and Calaf’s love duet, completed after Puccini’s death by Franco Alfano, feels like too easy a resolution and can’t help sounding a bit, er, 19^th century after what’s gone before. Adventurous listeners should seek out Berio’s much more radical 2001 attempt. Until that completion enters the repertoire, Opera North’s production will do, in spades. You can’t imagine Turandot being performed with greater gusto.

Born Alfred Arnold Cocozza to immigrant working-class Italian parents in Philadelphia, Mario Lanza was lauded by the likes of Serge Koussevitsky and Arturo Toscanini, becoming a huge Hollywood star by the early 1950s.

How well do you know your bad Victorian poetry? “When through the purple corridors the screaming scarlet Ibis flew/In terror, and a horrid dew dripped from the moaning Mandragores.” Go on, guess the author. Or how about this? “What time the poet hath hymned/The writhing maid, lithe-limbed,/Quivering on amaranthine asphodel". Got it yet? The first is Oscar Wilde’s The Sphinx, from 1881. The second, WS Gilbert’s libretto for Patience – written in the same year, and skewering Wilde with gleeful relish and lethal precision.

"È un'immensa pietà" - "it's heartbreaking," rather than "it's a huge pity" - sings consul Sharpless of "Butterfly" Cio-Cio San's fatal belief that her American husband will return to her.

Treasure our young continental European musicians in London while you can. Only last week I learned that so many of the overseas students at London's Guildhall School had stories to tell about being questioned in public (usually "are you Polish?" with the negative ramifications that implied). Certainly that was true for the Estonians, two of whom celebrated their country's 99th birthday as a republic yesterday lunchtime - the big day is on Friday; expect much more in centenary year - with assistance from their London embassy and the City Music Society.

“Who says Mozart is not like Rossini?” remarked Juan Diego Flórez, about a quarter of an hour into his debut recital at Symphony Hall. “There are seven high Cs in this aria.” And with a flicker of notes from the pianist Vincenzo Scalera, he was off into "Vado incontro", from Mitridate by the 14-year old Mozart. He wasn’t joking, either.
