Tim Albery’s 2010 production of Wagner's Tannhäuser is back for a revival at Royal Opera, featuring a different conductor and a nearly new cast, with one notable exception. The production itself is serviceable, visually coherent and with plenty of atmosphere. The sets, by Michael Levine begin with a replica of the Covent Garden proscenium arch in the Venusberg scene, which is then shown in progressive states of decay in the following acts. The Venusberg choreography, by Jasmin Vardimon, is modern and slick, as dynamic as it is sensual.

Lucia di Lammermoor is an opera in which men spend an awful lot of time talking about women, and very little actually talking to them. (Which, if nothing else, ensures a rather more dramatic denouement than a frank conversation about everyone’s hopes and dreams would produce.) Enter director Katie Mitchell and her “strong feminist agenda”, determined to give Donizetti’s women back their voices, and with them the agency every plot twist in the opera conspires to deny.

Some new operas worth their salt work a slow, sophisticated charm, but the handful that holler "masterpiece" grab you from the start and don't let go. Gerald Barry's shorn, explosive Wilde – more comedy of madness than manners – was so obviously in that league at its UK premiere in 2012, and has kept its grip in two runs of Ramin Gray's similarly against-the-grain production, now removed from the currently-closed Linbury Theatre at the Royal Opera House to the wider stage of the Barbican Theatre. It's still one of the few hysterically funny operas in the repertoire.

How ironic that English National Opera turned out possibly the two best productions of the year after the Arts Council had done its grant-cutting worst, punishing the company simply, it seemed, for not being the irrationally preferred Royal Opera. And while 2015 has been as good as it gets artistically speaking for ENO, 2016 may well see confirmation of the first steps towards its dismantling by a short-sighted management – for what is a great opera house without a big chorus or a full roster of productions, both elements under threat?

You can forgive a certain amount of scepticism. After his now-infamous Royal Opera debut earlier this year, directing a Guillaume Tell that was heavy on concept and light on just about everything else, Damiano Michieletto returns for a Cavalleria Rusticana/Pagliacci that sounded as though it might go the same way. In the flesh, however – and what work-calloused, life-blasted verismo flesh it is too – the production is thoughtful and instinctively theatrical – as good a new show from the company as we’ve seen all year.

The tale of Orpheus – a musician so talented his art could overturn the laws of the universe – is the originary myth of opera itself. Is it any wonder, then, that it’s a story that the genre continues to tell and retell with such care and fascination? Three versions, spanning almost four centuries from Rossi’s 1647 Orpheus to Little Bulb Theatre’s 21^st-century production, punctuate the current Royal Opera House season, starting with Gluck’s Orphée et Eurydice – seen for the first time in the company’s history in its French reworking.

September is upon us and it’s nearly time for the new season. English National Opera’s Artistic Director John Berry may have left the building but his enterprising legacy lives on in a 2015-16 season that looks on paper as good as any in the past 20 years; what happens after that is anyone's guess. Still, there shouldn’t be too much grief that ENO Music Director Edward Gardner has moved on, since his successor Mark Wigglesworth already has a fine track record with the company.

In 2007, a tiny British theatre company called 1927 staged their first ever show at the Edinburgh Fringe – the darkly reimagined collection of fairytales and fables Between the Devil and the Deep Blue Sea. Now, almost a decade on, they are back where it all began – not at the Fringe but the Edinburgh International Festival, with their acclaimed Komische Oper production of The Magic Flute.

Thresholds are breached and barred, penetrated and sealed up in Harrison Birtwistle’s beguiling pair of mythological scenas The Corridor and The Cure. Originally commissioned by the Aldeburgh Festival in 2009, The Corridor is paired here for the first time with Birtwistle’s new companion piece, in a production first seen this month at Aldeburgh and now at the Royal Opera House.

How many words would you expect in an average libretto? 10,000? 15,000? Whatever that number is you can triple it and then some for The Virtues of Things – a new opera from Sally O’Reilly and Matt Rogers of astonishing, exhausting, battering wordiness. And with all these extra words what does it have to say? Not a great deal, frankly.
