If last year’s Ring cycle triumphantly proved that world-class opera can be done at the Albert Hall, this Rosenkavalier suggests that the less epic end of the repertoire isn’t such a sure thing. That is not to say that this performance was dud, far from it; rather that its few problems were venue related. Balance was the main issue, though Robin Ticciati did a great job of whipping the London Philharmonic Orchestra into a passionate frenzy in the Prelude and then taking things down a notch and keeping them there to avoid engulfing the voices.

Some of us have witnessed Traviatas where single stars were born: Angela Gheorghiu for Solti at the Royal Opera nearly 20 years ago springs quickest to mind. Some would claim a dream couple in Anna Netrebko and Rolando Villazon on peak form at Salzburg. Yet how often in a lifetime do you catch an evening like this, where all three principals are not only up to the very highest vocal standards but also work as one with the conductor to make sense of every phrase, every word, in an intimate space for which Verdi's chamber opera might have been crafted?

One of the joys of attending an opera in the Concert Room at St George’s Hall, Liverpool, is the feeling that the audience is sitting in the set itself. Now one of the city’s foremost concert venues, this Victorian gem never ceases to amaze, even though it was reintroduced to active use in 2006 after extensive refurbishment. This summer and autumn, much of the Royal Liverpool Philharmonic’s musical activity has decamped to the venue as the Philharmonic Hall has closed for a multi-million pound refurbishment and partial rebuild.

Bakst’s harem drapes and Roerich’s smoking, steaming Polovtsian camp may not have had the most lavish of recreations. But the rest of this homage to Diaghilev shone with an exuberance and even a precision one would not have thought possible from previous seasons of what had once seemed like Andris Liepa’s Ballets Russes vanity project.

Buxton has gone Bohemian, digging into Dvořák’s treasure trove and celebrating Gluck’s tercentenary. The choice of Dvořák’s The Jacobin fits the Buxton Festival tradition of rooting out neglected works, since this has been unjustly overlooked since the first performance in 1889. It’s an irony that this makes Gluck’s Orfeo ed Euridice an unexpected choice, being ever-popular since 1762. However, artistic director Stephen Barlow has linked them for the festival’s two new home-grown productions for this, the 36th festival.

For my money, The Queen of Spades is one of the great nineteenth-century operas, a masterpiece of dramma per musica. There will always be pure spirits who cry “vulgar” at late Tchaikovsky. But the charge is absurd. Anyone with ears can hear the brilliance and refinement of this music, and anyone with feelings can sense Tchaikovsky’s love of his characters, all of them: the frail, the mad, the villainous, the beautiful and the damned. What more can you ask?

Rimsky-Korsakov’s bizarre final fantasy, puffing up Pushkin's short verse-tale to unorthodox proportions, has done better in Britain than any of his other operatic fairy-tales. That probably has something to do with its appearance in Paris, six years after the composer’s death in 1908, courtesy of a brave new experiment marshalled by that chameleonic impresario Sergei Diaghilev.

The latest in a series of "Pinnock’s Passions" concerts at the Sam Wanamaker Playhouse saw the doyen of period instrument performance lead a delightful exploration of Handel the musical borrower, entitled "Handel’s Garden". As Trevor Pinnock writes in the programme notes, "throughout his life as a composer he had the habit of taking cuttings, transplanting and grafting from works old and new".

The Royal Opera House’s Maria Stuarda is the third major production of Donizetti’s historical opera in less than two years. First there was David McVicar’s kitschy-traditional production for the Met, then there was Rudolf Frey’s baffling concept-drama at Welsh National Opera, and now directors Moshe Leiser and Patrice Caurier add their voices to a conversation still trying to make sense of these passionate warring queens with their determinedly dispassionate music.

Speaking from the stage before curtain-up on The Barber, Longborough’s founder and chairman, Martin Graham, stressed the hard work put in by director Richard Studer and conductor Jonathan Lyness on their two 2014 productions, this one and Tosca. He wasn’t kidding. Read the programme and you find (for both operas): director, Richard Studer; designer, Richard Studer; costume, Richard Studer. Lyness conducting both works.
