Celebrating the 80th anniversary of opera at Glyndebourne, this 90-minute documentary was fascinating when it delved into the house's history, but started to lose its bearings when it came back to the present day and dwelt at laborious length over this season's new production of Richard Strauss's Der Rosenkavalier. It was as if nobody could decide what sort of film to make, so they made two and cut chunks of them together.

“I feel so alone I could cry”. As the keynote of Adam Smallbone’s Passion in the breathtaking third series of Rev, that unspoken sentiment provided a passacaglia bass line to the failure of St Saviour’s. Made explicit In the mouths of possibly 600 Londoners just around the corner from that noble edifice, in reality the relatively thriving St Leonard’s Shoreditch, it felt paradoxically uplifting and – I feel myself sucked in to use the word now that I'm signed up to Spitalfields hip – empowering.

The Fall of the House of Usher is one of Edgar Allan Poe’s mistier tales, and although it has been turned into opera a few times, there are obvious difficulties. Debussy struggled for a decade to materialise a drama out of its haunting, neurotic atmosphere, and in the end failed, I would argue, because he was unable to distance himself enough from the central characters to construct a stage action about them.

Puccini’s racy first masterpiece, like its successor La bohème, should feel like an opera of two halves – the first full of youthful exuberance, the second darker and ultimately tragic. The contrast here, alas, was between vivacious performers and a sombre, sometimes confused updating by Jonathan Kent which too often dwarfed or zapped their better efforts.

Before curtain-up on the opening night of this revival of Penny Woolcock’s production of The Pearl Fishers, ENO's head of casting arrived on stage with a microphone. No doubt delightful company in person, he was an unwelcome sight here. Sophie Bevan had a stomach bug, he explained – the disappointment was palpable. But she'd be bravely singing anyway – grateful applause broke out. In the end, our goodwill was not called upon in the least, since Bevan's voice in her debut as Leïla was as strong and agile as ever.

What a red letter day it is when a work you’ve always thought of as problematic seems at last, if only temporarily, to have no kind of fault or flaw. That was the case for me on Sunday afternoon with Britten’s penultimate opera, Owen Wingrave, launching this year’s Aldeburgh Festival with an ideal cast fused as one with the young Britten-Pears Orchestra thanks to the self-evidently intensive collaboration of director Neil Bartlett and conductor Mark Wigglesworth.

The practical considerations and limitations of choosing a work for a student showcase can lead to some wonderfully original programming. It doesn’t get much more original than a pairing of Thomas Arne’s ballad opera The Cooper with Stradella’s oratorio San Giovanni Battista, currently being staged by the Guildhall School of Music and Drama.

How delicious that Garsington Opera has turned to Offenbach. The main impetus for this cheering development, taken up by Artistic Director Douglas Boyd, is conductor David Parry, who both translates (extremely well) and wields the baton.

Sex farce, class comedy, crime thriller, existential tragedy, supernatural shocker - Don Giovanni is, as Jonathan Kent notes about his production in the Glyndebourne programme, a cabinet of curiosities. Mozart's music hurdles to and fro across two centuries, the baroque 18th century and the disorientating romantic depths of the 19th; the characters are either stock (Leporello the comic sidekick, Anna the wronged virgin) or so subtle that they need redefining for every staging and every time (Elvira, and the lothario Don Giovanni himself).

Tumblers, confetti, stiltwalkers, flags, crowds, a giant skull, and that’s just the overture. If anyone thought that Terry Gilliam might struggle to match the scope, scale or impact of 2011’s Damnation of Faust with his follow-up then they’re probably feeling rather foolish right about now.
