Forget, for a moment, the legend and the lustre. If you knew nothing about Riccardo Muti’s half-century of history with Verdi’s Messa da Requiem for the writer-patriot Alessandro Manzoni – he first gave it with the Philharmonia back in 1974 – and came fresh to this conductor with this work, would it shake the soul? On the evidence of the 83-year-old maestro’s performance with the same orchestra at the Royal Festival Hall last night, the answer would have to be a resonant affirmative.

How many Rigolettos have regular operagoers among you sat through where there wasn’t some major defect, in either the production or the three major roles? Here, there is none. INO’s jester and Duke are well cast, its Gilda supernaturally perfect in music and acting, while Julien Chavaz’s production, despite a few passing irritations, adds up to a coherent and disciplined whole. INO Artistic Director Fergus Sheil keeps Verdi's vivid music theatre on the move.

How we used to mock those stuck-in-the-mud opera houses that wheeled out the same moth-eaten production of some box-office favourite decade after decade. Well, Jonathan Miller’s 1950s New York mafiosi version of Verdi’s Rigoletto first arrived on stage in 1982, after The Godfather (Parts I and II) but well before The Sopranos. For ENO at the Coliseum, Elaine Tyler-Hall has now directed its 14th revival. ENO has lately borne the brunt of drive-by funding massacres by the ruthless (and opera-loathing) capi who control the UK arts-subsidy game.

We were of course lucky to get this new WNO Rigoletto at all. If it weren’t for the fact that, in the end, the company’s wonderful chorus and orchestra couldn’t wait to get back to doing what they do best, and accepted a modest glow of light at the end of the tunnel that would barely have registered on the light meters of most union negotiations, the company could well have been dark for many months, perhaps for good.

Later this autumn Richard Eyre’s La Traviata celebrates its 30^th birthday. Not bad going for the director’s first ever foray into opera – a genre he admitted holding an “unreasonable prejudice against”.

The Philharmonia’s residency was the centrepiece of the Edinburgh International Festival’s final weekend, and it’s right that the orchestra should be the focus because they were consistently the finest thing about both their Verdi Requiem and their concert performance of Richard Strauss’ last opera Capriccio.

Returning after ten months to the unique vasts of Albert’s colosseum, especially for a Verdi Requiem as powerful as this and a packed hall, felt like a rebirth. There was immediate purging in the focused whispers of the first “Requiem aeternam”s, BBC National Orchestra of Wales Principal Conductor Ryan Bancroft instilling a confidence you knew would last the evening, and instant thrills in the clarion “Kyrie”s of all four world-class soloists.

If ever more evidence were needed of Sir Mark Elder’s untiring zest for exploration and love of the thrill of live opera performance, it was this ground-breaking collaborative event with Opera Rara – a performance coupled to a new studio recording of the original version of Verdi’s Simon Boccanegra.

Antonio Pappano is at a hinge in his illustrious career, as the exciting transfer across London from Covent Garden to the London Symphony Orchestra proceeds, and the word "Emeritus" is added to his title as Music Director of his home-from-home in Rome. A good moment, then, for him to make a statement of commitment to the latter, with a shattering, searing account of probably the most terrifying piece of music ever written: Verdi’s incomparable Messa da Requiem.
