The team of Stephen Langridge (director), Alison Chitty (design) and Paul Pyant (lighting) produced a quietly radical Parsifal at the Royal Opera in 2013, finding both beauty and horror in unexpected corners. On the strength of its third instalment – I haven’t seen the first two – their Ring in Gothenburg pursues a no less subtle course of rebellion against some tenaciously held conventions and traditions in staging Wagner.

The Hallé have been slow off the mark, compared with some, in their response to the challenge of concert-giving in the Covid era. But now that they have delivered on the first of their winter season performances, it has clearly been worth the wait.

GogolFest:Dream in Kherson, somewhere near the Crimea in Ukraine was the music festival of the summer. Admittedly, in my case and for many, having missed out on WOMAD, Glastonbury, Fez, and others it was the only festival of the summer, and the bar didn’t have to that high to satisfy a festival junkie in need of a fix.

It's taken time, but at last we have two major musical figures speaking up for cultural institutions in dire straits. Following a crucial, detailed article by Charlotte Higgins in The Guardian, Simon Rattle and Mark Elder have finally taken up the cudgels as their colleagues in the theatre world have been doing for weeks.

Wagner's final drama, of learning, suffering and redemption through compassion, is second only to Bach's Passions at this time of year, and seems likely to strike a special note in the present crisis. Opera companies around the world, making much in their archives free to view right now, have served up the natural seasonal choice, and they have: there are at least nine choices right now, and they come from the expected centres of excellence including Berlin, Vienna, Munich, New York.

Of Wagner's four Ring operas, Siegfried poses the biggest casting problem. Most heroic tenors with the lungs to last the evening are not going to be ideal incarnations of the stroppy adolescent who learns and fights his way through an often nightmarish fairy-tale landscape. Torsten Kerl, not an agile mover to say the least, certainly wasn't.

People who derive comfort from Classic FM’s strapline that European classical music is “The World's Greatest Music" are going to have a major problem with this book. American music historian Ted Gioia has marshalled 25 years' worth of his own life and several centuries of music history into 500 pages which put that complacent assertion in doubt.

“The scope of this book is the full history of music,” he writes in his introduction. And his aim? "Above all, I hope to topple established hierarchies and rules, subverting tired old conventions and asserting bold new ones."

Known as "Heldenmommy" to her fans on Twitter, Christine Goerke is a Wagner soprano of and for our time. You won’t find her recordings on the major-label behemoths but her reputation is built on two decades of producing the goods night after night at opera houses across the US, notably the Metropolitan in New York. On the other side of the Atlantic, her Brünnhilde has filled the Usher Hall through the course of a four-year Ring cycle at the Edinburgh Festival.

Anna Larsson's fellow Swedes can count themselves lucky that the worldwide first choice to sing Wagner's Erda and the midnight song in Mahler's Third Symphony has made so much of her Dalarna inheritance.

The whole raison d’être of the Longborough Festival was always the performance of its founder Martin Graham’s beloved Wagner.
