Keith Warner’s production of Wagner's Der Ring des Nibelungen was first seen at Covent Garden between 2004 and 2006, and is now back for a third and final series of full runs, chiefly to catch the Brünnhilde of Nina Stemme in three of the operas, continuing into November.

It's Britten outside-in time for English National Opera. Regent's Park Open Air Theatre, which played host earlier this year to an only partially convincing production of his 1950s masterpiece The Turn of the Screw, would have been the perfect choice for the prelapsarian American forests of his pre-Grimes operetta/musical Paul Bunyan.

It’s an event that only comes around once a generation: a new Matt Groening TV series. The Simpsons is rightly regarded as one of the greatest shows ever made. It changed the face of American television, and 10 years later was followed Futurama, a series that may lack the cross-demographic appeal of its predecessor, but consistently produced satirical masterpieces.

Considering the coal-dark nature of her music, it was unsurprising Sweden's Anna von Hausswolff was dressed entirely in black while meeting up at London’s Rough Trade East shop to talk about her new album Dead Magic. Less foreseeable was her sunny disposition and willingness to veer off topic. She happily explored what has brought her to this point and spoke enthusiastically about her inspirations.

Vladmir Jurowski and the London Philharmonic Orchestra have been to the bottom of the Rhine before, but in 2015 only did a whistlestop tour of the rest of Rheingold's terrain with an extensive array of excerpts.

The power of music solves every problem, at least when as bewitchingly performed as it was here. With the great mezzo Christine Rice voiceless for at least a night, and rising star Caitlin Hulcup singing for her from the midst of the instruments in the pit right at the centre of the Roundhouse, how could faithful Penelope's final acceptance of her long-lost husband Ulysses (Roderick Williams) achieve transcendence?

Twelfth Night, Epiphany, call it what you will, is one reminder that there's continuity after the turn of the year. Another was Sakari Oramo's final Sibelius-plus concert with the BBC Symphony Orchestra - a predictable triumph given that the previous four were all highlights of 2017, capping, at least for me, the "Rattle Returns" experience.

If you're not going to mention the imaginative genius of Stravinsky, Auden and Kallman within the covers of your programme, and the only article, by the director, is titled "Acting Naturally", then the production had better deliver.

It has long been a mystery why no new production of Semiramide should have been staged at Covent Garden since 1887: un offesa terribile considering that this splendid melodramma tragico should have been the inaugural production of the Royal Italian Opera House (our current theatre’s predecessor) in 1847.

It’s official: Romanian master George Enescu’s four-act Greek epic lives and breathes as a work of transcendent genius. It took last year’s Royal Opera production to lead us further along the path established by the magnificent EMI studio recording with José van Dam as protagonist.
