Agrippina, Royal Opera review - carry on up the Campidoglio

★★★ AGRIPPINA, ROYAL OPERA Carry on up the Campidoglio

Vamping, stamping and men-babies on stage, a capricious beast in the pit

It was said of the Venetian audiences randy for the satirical antique of Handel's first great operatic cornucopia in 1709 that "a stranger who should have seen the manner in which they were affected, would have imagined they were all distracted".

Werther, Royal Opera review - shadows and sunsets from an unreconstructed romantic

★★★★ WERTHER, ROYAL OPERA Shadows and sunsets from an unreconstructed romantic

Massenet's opera shines bright, notwithstanding a slightly clunky hero

Goethe’s Die Leiden des junges Werthers (The Sorrows of Young Werther) was a vital spark in the ignition of the German romantic movement. The story of a young man driven to kill himself for love of a woman, Charlotte, who loves him but marries someone else out of duty to her family, it was first published in 1774. It triggered a fever across Europe ranging from fashion trends (Werther wears blue with a yellow waistcoat) to a spate of copycat suicides. Among its admirers were Beethoven, Brahms, Napoleon and Frankenstein’s Monster.

Don Giovanni, Royal Opera review - laid-back Lothario

★★★ DON GIOVANNI, ROYAL OPERA Laid-back Lothario

Revival cast variable, but Erwin Schrott delivers as the would-be seducer

Kasper Holten left a mixed bag of productions behind at Royal Opera when he left in 2017, but the best of them - though not all my colleagues on The Arts Desk have agreed - is this Don Giovanni, now back for its latest revival.

La Fille du Régiment, Royal Opera review - enjoyable but questionable revival

★★★ LA FILLE DU REGIMENT, ROYAL OPERA Enjoyable but questionable revival

Tenor Javier Camarena excels in an otherwise only serviceable account

On paper, this might seem like a revival too far, a production clearly intended as a vehicle for world-class singers being tacked on the end of the Covent Garden season, and without any big names in sight. But it turns out that Laurent Pelly’s staging, now in its fourth London return, has enough charm and substance to justify an outing with lesser names.

Boris Godunov, Royal Opera review - cool and surgical, with periodic chills

★★★★ BORIS GODUNOV, ROYAL OPERA Cool and surgical, with periodic chills

The conscience of Bryn Terfel's tsar-king's the focused thing in this immaculate revival

Suppose you're seeing Musorgsky's selective historical opera for the first time in Richard Jones's production, without any prior knowledge of the action. That child's spinning-top on the dropcloth: why? Then the curtain rises and we see Bryn Terfel's troubled Boris Godunov seated in near-darkness, while a figure with an outsized head plays with a real top in the upper room before being swiftly despatched by three assassins. The playback repetitions are the thing to catch the conscience of the tsar-king.

The Diary of One who Disappeared, ROH review – song cycle-as-opera is a mish-mash

Padding out Janáček’s work with extraneous material merely diffuses the music’s power

Singer Ian Bostridge once described The Diary of One who Disappeared as “a song cycle gone wrong”. But this reimagining of it as an opera, by the Belgian director Ivo van Hove at the Royal Opera’s Linbury Theatre, also goes wrong, throwing in various extras which detract from rather than enhance the piece’s impact. I am no stranger to being baffled in an opera house.

Phaedra, Linbury Theatre review - from confusing passion to blazing afterlife

★★★★ PHAEDRA, LINBURY THEATRE From confusing passion to blazing afterlife

Henze's near-death experience gives this skewed mythology extraordinary life

Leaving a revival performance of Harrison Birtwistle's The Minotaur, a friend asked Hans Werner Henze, also in the audience, that dreaded question: "what did you think?" "Very competent and extremely well performed," came the answer.

Billy Budd, Royal Opera review - Britten's drama of good and evil too much at sea

★★★ BILLY BUDD, ROYAL OPERA Britten's drama of good and evil too much at sea

Peerless protagonist among a crew sometimes lost on an infinite stage

On one level, it's about Biblically informed good and evil at sea, in both the literal and the metaphorical sense. On another, the love that dared not speak its name when Britten and E M Forster adapted Hermann Melville's novella is either repressed or (putatively) liberated. The conflicts can make for lacerating music theatre, as they did in Orpha Phelan's production for Opera North.

Faust, Royal Opera review - fusty Gounod still dances

★★★ FAUST, ROYAL OPERA Lively conducting and last-minute replacement enliven hellish cabaret

Lively conducting and a last-minute replacement keep this hellish cabaret on its toes

Goethe's cosmic Faust becomes Gounod's operatic fust in what, somewhat surprisingly, remains a repertoire staple. You go for the tunes, hoping for the world-class voices to do them justice and prepared for a pallid quarter-of-an-hour or two.
