Kurt Cobain’s “Smells like Teen Spirit’ cued a realistic song and drink routine for Chekhov’s Three Sisters in a hit-and-miss update by director Benedict Andrews. This one, with a Puccini soundtrack unsupportively conducted by Xian Zhang, smells more like routine spirit with a couple of jolts along the way, a sludgy requiem for drug-fuelled twenty-somethings.

“The music quacks, hoots, pants and gasps”: whichever of his Pravda scribes Stalin commandeered to demolish Shostakovich’s “tragedy-satire” in January 1936, two years into its wildly successful stage history, didn’t mean that as a compliment, but it defines one extreme of the ENO Orchestra’s stupendous playing under its new Music Director Mark Wigglesworth. On the other hand there are also heartbreaking tenderness, terrifying whispers and aching sensuousness.

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.

The delicacy of its supernatural elements make Pushkin’s The Queen of Spades, as adapted by Tchaikovsky, a tricky proposition for any director. Do you go with the ghost story and risk losing your audience emotionally, or do you play it straight, trying to rationalise the plot’s moments of macabre? The hands of the clock stand perpetually arrested just moments before midnight in David Alden’s new production for ENO, putting his audience out of any doubt as to which he has chosen.

When ENO announced its return to Gilbert and Sullivan, rapture at the news that Mike Leigh, genius Topsy-Turvy director, would be the master of wonderland ceremonies was modified by its choice, The Pirates of Penzance. Last staged at the Coliseum – and unmemorably – as recently as 2004, the fifth Savoy opera seemed less in need of revisiting than several larger-scale successors.

Composer Tansy Davies and librettist Nick Drake’s opera Between Worlds cannot help but be a devastating tribute to the tragedy of 9/11. Yet the whole is peppered with problems that mean this result is achieved only intermittently. Davies – whose first opera this is – and the playwright Drake, with Deborah Warner directing, have picked a topic that would seem at first glance to demand the scale of a modern-day Götterdämmerung. The result they extrapolate is far from that – but when it does succeed, it is in ways that are not really about 9/11 at all.

From Singin’ in the Rain and Anything Goes to Hello, Dolly! and Mary Poppins, Olivier Award winner Stephen Mear has done more than any other British choreographer to usher classic musicals into the modern era. But adept as he is at razzle-dazzling ’em, there’s more to Mear, as recent excursions like City of Angels at Donmar Warehouse and Die Fledermaus for the Metropolitan Opera prove.

Still they keep coming, 35 years on from the London premiere of Sondheim's "musical thriller": Sweeneys above pubs, in pie shops, concert halls and theatres of all sizes, on the big screen, Sweeneys with symphony orchestras, two pianos or a handful of instruments wielded by the singers, Sweeneys as musicals and as operas, the dumpy and the tall. Which type was this one? Not a vintage English National Opera production, that much seems clear.

Having been bowled over by the total work of art English National Opera made of Wagner’s The Mastersingers of Nuremberg on its first night, I bought tickets immediately afterwards for the final performance. So I’m off tonight to catch the farewell of what has been an unqualified triumph for the company. Yet only last Thursday an unsolicited email arrived from Amazon Local – there’s no stopping them, it seems – offering tickets for this very show at 40 per cent discount.

When Purcell died at just 36, he left The Indian Queen unfinished, which only adds to the usual problems of staging his "semi-operas" – plays with musical interludes which don’t really accord with modern operatic tastes, despite the ravishing beauty of the music itself.
