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.

After exhausting years of financial and artistic crisis-management at the Coliseum, English National Opera urgently needed an ironclad, feelgood success. This season’s opener, a somewhat idiosyncratic take on Strauss’s Salome, was unlikely to fit that bill.

There was no synopsis in the programme for the Royal Opera’s concert performance of Handel’s Solomon. Maybe that was an oversight, but perhaps it’s simply because there really is no plot to summarise.

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.

Baroque repertoire doesn’t seem to register on most British opera company’s schedules these days, so it is good to see ETO devoting their autumn season to Handel, Purcell and Bach, with some additions from Carissimi and Gesualdo for good measure. Their first production, Handel’s Radamisto, is a good choice for touring, a compact six-hander with strong characters and great music.

Two days after announcing his appointment as their next chief conductor (he takes the reins officially next summer, in time for the Proms), by remarkable good fortune the Manchester-based BBC Philharmonic was able to present Omer Meir Wellber as the conductor of their second Bridgewater Hall series concert.

Her special claim to fame was the most luminous pianissimo in the business, but that often went hand in velvet glove with fabulous breath control and a peerless sense of bel canto line. To know Maria de Montserrat Viviana Concepción Caballé i Folch, born in Barcelona 85 years ago, was clearly to love her. I never did (know her, that is), and I only saw her once, in a 1986 recital at the Edinburgh Festival. By then she was careful with her resources, but the subtly jewelled programme delivered on its own terms.

 “War Horse has a lot to answer for,” grumbled, or joked, my neighbour as the white-draped and white-faced puppet of the Queen of Carthage lay crumpled on the floor at the close of Thomas Guthrie’s semi-staged production of Dido and Aeneas. Well, not just War Horse.

And so it ends. Flames give way to water, and as the Rhinemaidens resume their naked dance we come full circle – quite literally in Keith Warner’s Wagner Ring – back where we began, on the banks of the Rhine. Once again we find ourselves on the brink – but of what? A young woman framed in the giant ring that descends in the music’s final moments suggests a hopeful new beginning, a new generation of heroes.

Siegfried is usually the problem with Siegfried. Even Stuart Skelton, top Tristan and currently singing an acclaimed Siegmund in this last revival of Keith Warner's rattlebag Ring, won't touch the longest, toughest heroic-tenor role in Wagner, the protagonist of his third opera in the tetralogy.
