Sunken Garden is described officially as a “film opera”. Two words. Emphatically unhyphenated. No attempt made to neologise or fashion some third-way genre terminology. It’s not a symbol that bodes well for mutually-informed, sensitive interdisciplinary thinking, but in Michael Van der Aa and David Mitchell’s work English National Opera have come one tiny, shuffling step closer to realising that elusive multimedia idée fixe that has so preoccupied the company under John Berry.

A toast to London’s Handel Festival, now celebrating its 36^th year, and to Ian Page’s adventurous Classical Opera Company, for pulling Telemann out of the drawer and placing him in the forefront of this year’s celebrations at St. George’s, Hanover Square. 

Like Prokofiev’s The Love for Three Oranges and Puccini’s Turandot, Wagner’s first opera – The Fairies in English – has its roots in a “theatrical fable” by the 18^th century Venetian playwright Carlo Gozzi. There the resemblances end. Only Prokofiev follows Gozzi’s playful mix of commedia dell’arte and fairy-tale characters. The 20-year-old Wagner has one moment of fun – cut in this performance – but a mere handful of musical gestures and plot devices prophesying greatness to come rises to the surface in this gloopy mess.

“I do not believe in miracles,” scoffs Herodias in Oscar Wilde’s -  and Richard Strauss’s - Salome. “I have seen too many.” I know how she feels. So it was a bit of a shock to find the highest-kicking of today’s composers, John Adams, and his inseparable genius director Peter Sellars, taking the raising of Lazarus seriously in the first part of their latest opera-oratorio (my term, not theirs, and also applicable to El Niño, Adams’s millennial take on Christ’s birth and its concomitant hazards).

Imago, Glyndebourne’s latest Community Opera exercise, putting the cap on 25 years of pioneering educational outreach, is one of those operas where you need to read the programme synopsis first. 

Simon Boccanegra has, as English Touring Opera’s director James Conway points out, never quite made the running outside Italy amid Verdi’s output. It went through three to five different versions in a short space of time. Despite the Romeo and Juliet era setting (14th-century Genoa battling it out with Venice) there are naivetes in Piave and Boito’s plot which, despite the frenetic story’s many merits, generate more than the usual operatic implausibilities.

It’s hard to put one’s finger on why George Benjamin’s new opera doesn’t work. It comes to Covent Garden with a wind in its sails. Its outings in Europe have all received high praise. It boasts a classy cast, Martin Crimp as librettist and Benjamin at the helm of the orchestra. The story is a captivatingly horrific medieval morality tale that often goes by the title of "the Eaten Heart story". And there’s little wrong with Katie Mitchell’s production.

Excess of light and heat sends sun-god Apollo’s son Phaeton tumbling from his father’s chariot. The light was iridescent and the temperature well conditioned as peerless Christophe Rousset led his period-instrument Les Talens Lyriques and a variable group of singers through a concert performance of Lully’s 1684 tragédie-lyrique, a specially pertinent, heliotropic operatic homage to le roi soleil Louis XIV.

Who’d have guessed a full house for the third of The Rest is Noise festival’s Berlin nights? This time there were no obvious superstars, unless you follow singer-songwriter Shara Worden of My Brightest Diamond and you know the impeccable track-record so far of young conductor André de Ridder.

Given a fair few strange and languishing Brecht-Weill pieces that The Rest is Noise Festival’s Berlin strand might have explored, Vladimir Jurowski and the LPO had a tough time of it by piecing together a performing edition of the most familiar one. Stagings of Die Dreigroschenoper with singing actors and a deft director can knit this celebrated hybrid together.
