Could there be more tender, tactful or soul-nourishing signs of a new musical normal than these two 45-minute gems? We're nowhere near emulating the kind of live distance concerts members of the Bergen, Oslo and Czech Philharmonics have been offering for some weeks now, but it's vital to hope that we can at some point in the not too distant future.

Could English National Opera be about to right the wrong done to a national treasure?

Wigmore Hall audiences don’t usually roar. But when a star soprano who has already made her mark at the world’s major opera houses pays a visit, they do.

There's no question about my top opera choice for 2019, especially since the London houses rarely delivered at the same pitch of engagement. It's Graham Vick's walkabout Birmingham Opera Company spectacular, a production of Shostakovich's Lady Macbeth of Mtsensk that worked on every level.

There is no doubting Diana Damrau’s star power. She is not a demonstrative performer, and her voice is small, but the sheer character of her tone, and the passion she invests, make every line special. She is not one to over-sentimentalise either, so there was never any danger of Strauss’s Four Last Songs turning saccharine here.

With eyes swivelled towards who'll take over from Esa-Pekka Salonen as the Philharmonia's Principal Conductor in 2021, two of the strongest possibilities are to be found within the orchestra's masthead of associates.

Presenting the last Mozart symphonies as a three-act opera for orchestra, as Richard Tognetti and his febrile fellow Australians did on Monday, was always going to be a supreme challenge. It worked, as Boyd Tonkin reported here. Since then, the Barbican's grandiosely-named "International Associate Ensemble" has opened up the repertoire, synchronising with film (on Tuesday) and ending its mini-residency with the kind of vibrant rattlebag for which it's rightly celebrated.

Here it comes - get a grip. The tears have started flowing in the trio "Quid sum miser" and 12 minutes later, as the tenor embarks on his "Ingemisco" solo, you have to stop the shakes turning into noisy sobbing. The composer then lets you off the hook for a bit, but only transcendent beauty in singing and playing can achieve quite this effect in Verdi's Requiem.

Why are great Wagnerian singers the most down-to-earth and collegial in the world of opera? Perhaps you have to be to master and sustain the biggest roles in the business, ones which can't be performed in isolation, and a strong constitution helps, too. Birgit Nilsson, the farmer's daughter born in rural Sweden 100 years ago, had all those qualities and many more.

Latvia is fighting fit. The recent elections did not see the expected victory for the pro-Kremlin Harmony party; support for the European Union and NATO will be well represented. Last week the feisty Lavtian Ambassador to the UK, Baiba Braže, landed a perfectly diplomatic punch on the smug mug of our latest apology for a Foreign Secretary, taking former Remainer Hunt to task for his outrageous parallels between the EU and the Soviet gulag by reminding him how Latvia had suffered under the USSR and how eagerly it has adopted the best European values.
