If you ever doubted that Bizet’s Carmen, 150 years young next year, is one of the greatest operas of all time, this performance would have changed your mind. Among the four principals only Rihab Chaieb’s utterly convincing, consistent protagonist was the same as on first night 22 performances ago, and as ringleader we had the vivacious conductor of the second run, Anja Bihlmaier.

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.

On opening night, there’s always a little tension in the air. Tech rehearsals and previews can only go so far – this is the moment when an audience, some wielding pens like scalpels, sit in judgement. Having attended thousands on the critics’ side of the fourth wall, I can tell you that there’s plenty of crackling expectation and a touch of fear in the stalls, too. None more so than when the show is billed as a new musical.

I’m all in favour of the EIF taking artistic risks, and of them bringing a high-prestige international production to Edinburgh. This Marriage of Figaro from Berlin’s Komische Oper is both of those things, because it is the first production by Kirill Serebrennikov – the high profile Russian director, placed under house arrest by the Putin regime, now based in Berlin – to be seen in the UK.

Immersive opera such as this can be tricky to pull off, but the magic of Roxana Haines’s new production of Stravinsky’s Oedipus Rex lies in its simplicity, letting the material organically weave around the audience without overcomplications or deliberately clever trickery.

“One charming night gives more delight than a hundred lucky days”. So claims one of the gorgeous (and, in this case, risqué) numbers that stud Purcell’s “semi-opera” The Fairy Queen like sequins on a flamboyant party gown.

Richard Strauss described conducting Wagner’s Tristan und Isolde for the first time as "the most wonderful day of my life". It’s understandable that Glyndebourne’s music director Robin Ticciati should wish to improve upon “wonderful” in conducting a concert staging in 2021 with "miraculous" in charge of the full Nikolaus Lehnhoff production. I challenge anyone to cite another Tristan more alert to every possibility – the electrifying, the ferocious, the transcendental.

For 50 years Clonter Opera, the song-on-the-farm project in rural Cheshire, has been encouraging would-be opera stars by giving them a chance to perform in undemanding conditions under the guidance of experienced professional.

It all began with audiences sitting on straw bales in a barn, and only after a purpose-built theatre came into being was there a small pit enabling something more than piano accompaniment for major productions.

Could “Cav and Pag” give way to “Sue and Pag”? As a double-bill partner for Leoncavallo’s backstage shocker Pagliacci, Opera Holland Park have scheduled not the standard Cavalleria Rusticana but an entirely different one-act work. Premiered in Munich in 1909, Wolf-Ferrari’s Il Segreto di Susanna plays droll, even farcical, variations on the same theme of male jealousy as newlywed Count Gil suspects his bride Countess Susanna of having an affair. 

Buxton International Festival offers one thundering success, one uneasy compromise and one surprisingly enjoyable experience, in its three mainstage operas this year.
